| CVE-2026-112174 | 1 Enter | 1 Iperius Backup | 2026-11-11 | N/A |
| Local privilege escalation vulnerability in Iperius Backup 8.8.3, due to insufficient separation between the graphical user interface running with elevated privileges and local users with low privileges. When the backup service is configured to run persistently with Administrator privileges, a local attacker with low privileges can use the native Windows dialogues exposed by the application to run programmes that inherit its elevated context. This allows commands to be executed with SYSTEM or Administrator privileges, depending on the application’s context, and compromises the affected Windows system. | ||||
| CVE-2026-124737 | 1 Redhat | 2 Hummingbird, Rhel Els | 2026-11-11 | 7.5 High |
| A flaw was found in BusyBox. When the TFTP (Trivial File Transfer Protocol) client requests a custom small block size and receives a standard response, it falls back to the default block size without resizing the allocated memory buffer. A malicious TFTP server can exploit this issue by sending standard-sized network packets during a transfer, causing a heap buffer overflow. This flaw allows an attacker to achieve arbitrary code execution or cause a Denial of Service (DoS) by crashing the application. | ||||
| CVE-2025-0604 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-11-11 | 5.4 Medium |
| A flaw was found in Keycloak. When an Active Directory user resets their password, the system updates it without performing an LDAP bind to validate the new credentials against AD. This vulnerability allows users whose AD accounts are expired or disabled to regain access in Keycloak, bypassing AD restrictions. The issue enables authentication bypass and could allow unauthorized access under certain conditions. | ||||
| CVE-2026-92091 | 1 Redhat | 5 Ansible Automation Platform, Enterprise Linux, Openshift Ai and 2 more | 2026-11-11 | 5.9 Medium |
| A flaw was found in jwcrypto. The JWK.import_key() function validates the key_ops JWK member for duplicate values using an algorithm with O(n^2) time complexity, and the length of key_ops is not bounded. A remote, unauthenticated attacker can supply a JWK with a large key_ops array to an application that passes attacker-controlled key material to a public key-import API (reachable via ECDH-ES key agreement, OIDC dynamic client registration, DPoP, or ACME account key registration, among others) to consume excessive CPU time, resulting in a denial of service. | ||||
| CVE-2026-80179 | 2 Red Hat, Redhat | 6 Red Hat Openshift Ai (rhoai), Ansible Automation Platform, Enterprise Linux and 3 more | 2026-11-11 | 5.9 Medium |
| A flaw was found in jwcrypto. A remote attacker can send a specially crafted JSON Web Encryption (JWE) token containing numerous period delimiters. This malformed token can force the JWE.deserialize() function to allocate excessive memory, leading to a MemoryError. This issue results in a denial of service (DoS) for services that process untrusted JWE values. | ||||
| CVE-2026-126626 | 2026-11-11 | 5.3 Medium | ||
| The web services listener of Progressive Robot hMailServer 6.3.3 through 6.3.7 counts every failed CardDAV, CalDAV or Autodiscover sign-in from a proxy it trusts - one on the same machine, or one named in WebServicesTrustedProxies, whose X-Forwarded-Proto it believes - against the proxy's own address, which allows a remote unauthenticated attacker who can reach the proxy to have that address banned from the server's mail listeners. The listener, off by default (WebServicesHttpPort and WebServicesHttpsPort 0), signs an account in with HTTP Basic over HTTPS for CardDAV from 6.3.3 and for CalDAV and Outlook Autodiscover from 6.3.4. Behind a TLS-terminating proxy, which the server trusts when it is on the same machine or named in WebServicesTrustedProxies, the listener takes the client's HTTPS from the proxy's X-Forwarded-Proto header, but it does not believe X-Forwarded-For and sees the proxy's address for every client. Each failed sign-in counted towards the auto-ban against that address, so that failed sign-ins through the proxy from anybody, under any user name, reaching MaxInvalidLogonAttempts (3 within 30 minutes by default) wrote an IP range that refused the proxy's address at the SMTP, POP3, IMAP and ManageSieve listeners for AutoBanMinutes (60 by default), and could write it again each time it lapsed. For a proxy on the same machine that address is the loopback address, so that a webmail on that machine, local scripts that submit mail and the other local clients of the mail listeners were shut out; for a proxy at another address that also carries mail, every mail client behind it was. Such a proxy forwarding to the listener's HTTPS port, re-encrypting, was counted against in the same way, and listing it in WebServicesTrustedProxies did not spare it. The auto-ban is on by default and AutoBanNeverBan, which spares an address, is empty by default; the listener itself went on serving the proxy. | ||||
| CVE-2026-79655 | 2 Red Hat, Redhat | 3 Enterprise Linux, Enterprise Linux, Rhel Els | 2026-11-11 | 7.8 High |
| A flaw was found in sos clean, a utility within the sos package. This vulnerability allows a local attacker to perform arbitrary file creation or overwrite. By crafting a malicious tar archive, an attacker can exploit a path traversal issue during tar extraction, where symlink and hardlink targets are not properly validated. This enables the attacker to write files to arbitrary locations on the system with the privileges of the sos clean process, which often runs as root. | ||||
| CVE-2026-126621 | 2026-11-11 | 7.5 High | ||
| Progressive Robot hMailServer 6.0.0-B1 through 6.3.7 on Windows hands OpenSSL the names of its own TLS files - the listeners' certificates, chains, private keys and Diffie-Hellman parameters, a port's client-certificate CA file (from 6.2.19), the object store's CA file (from 6.3.4) and the ACME client's keys and certificates - as Latin-1 bytes, which on code page 1252 are the code page's own for U+00A0 to U+00FF, and OpenSSL's file opening on Windows reads a name as UTF-8 first and opens the file at that reading when it is there, or creates it there when its folder is. When every byte of a configured name outside ASCII also reads as UTF-8 - for example U+00C3 U+00A9, the bytes C3 A9, which are U+00E9 in UTF-8 - the server used the file at that other name whenever one was there, which allows a local attacker who can create that file or its folder but cannot change the configured one, as any user can by default beside a file an administrator keeps under ProgramData, to have a port that logs on by client certificate (from 6.2.25) accept certificates from a certificate authority of the attacker's own and so sign in over the network as any mailbox without its password; to have the server trust such an authority for its object store and, intercepting that connection, read and modify the messages it stores; to receive the private keys the ACME client writes, the key of a certificate issued for the server's names among them; or to keep TLS ports from starting. The configuration is not the default: by default these files have names in ASCII, client certificates are off on every port, and the object store and ACME are off. The Linux builds are not affected. | ||||
| CVE-2026-126619 | 2026-11-11 | 4.8 Medium | ||
| Misinterpretation of SQL statement text in the database layer of Progressive Robot hMailServer 6.0.0-B1 through 6.3.7 allows a remote unauthenticated attacker to have a failed database write reported to the server as successful. The layer answers a failed statement as a success when it finds the marker [IGNORE-ERRORS], which is meant only for the server's own schema statements (its upgrade scripts and the database log's tables), and statements carry values from outside - an envelope address, the user name of a failed logon, a message's headers - in their text on MySQL/MariaDB and PostgreSQL, and in the batches of the database log on every engine. Up to 6.2.18 the marker was honoured anywhere in a statement, a value included, on MySQL/MariaDB and PostgreSQL. From 6.2.19 it was honoured only inside a comment, but the layer read a backslash inside a string literal as an escape, which SQL Server, SQL Server Compact and PostgreSQL with standard_conforming_strings on (its default) do not, so that on those engines a value holding a backslash could make the layer take part of the statement's literals for statement text and find the marker there: on PostgreSQL from 6.3.3 for every statement carrying an outside value that holds a backslash, with no setting changed for a message delivered into a local mailbox (through an internationalised (SMTPUTF8) envelope sender) and for the IP range an auto-ban writes (named after the user name of the failed logon), and on SQL Server and SQL Server Compact for the database log, when the server logs to the database (logging is off, and the log device is files, by default). A statement run outside a transaction that then failed - a constraint, a deadlock, a lock or statement timeout, a full disk, and up to 6.2.18 a lost connection - was answered as a success, and its caller went on as if the row had been written: a message delivered into a local mailbox could be counted as delivered with no row to show it and no failure notice to its sender, and a message accepted with 250 could be left with no queue row and never delivered (up to 6.2.18, and on PostgreSQL from 6.3.3 when every recipient's address carries the marker too, which needs an address that takes any local part); an auto-ban whose IP range was not written could be logged and counted as applied, with no error reported, while the address stayed unbanned; and message metadata (written only when message indexing is on), entries of the database log and rows of features an administrator turns on could be lost without an error. On MySQL/MariaDB up to 6.2.18 the caller was handed whatever identifier the client library still held for the connection - 0, or that of an insert its last successful statement made, in whatever table - under which a queued message's recipients were then written, so that another message still in the queue could be delivered to them as well. This flaw gives a value no way to change what a statement does, and no privilege is gained. | ||||
| CVE-2026-126617 | 2026-11-11 | 8.8 High | ||
| SQL injection in the database layer of Progressive Robot hMailServer 6.0.0-B1 through 6.2.18, when the server uses MySQL/MariaDB or PostgreSQL, allows a remote attacker to alter SQL statements the server runs. On those two engines parameters are not bound: SQLStatement::GenerateFromCommand wrote each value into the statement's text as a quoted literal with a separate string replacement over the whole text per parameter, so a value holding the name of a parameter substituted after it had that name replaced, inside the value, by the later value with its own quotes, which ended the literal early and placed the later value in the statement as SQL. The row the server writes for each recipient of a queued message carries the recipient's address twice, so in the default configuration an authenticated user who may send mail reaches it by sending to an address of their choosing. A remote unauthenticated sender reaches the same statement through a message the server sends to the envelope sender, such as a delivery failure notice or an automatic reply, and, when greylisting or message indexing is enabled (both are off by default), through the greylisting record's envelope addresses or through the message metadata the server stores for IMAP SORT, which carries four header fields of a received message. An altered statement runs with the privileges of the server's database account; on PostgreSQL, whose client call runs every statement in the text it is given, further statements can follow it, while on MySQL/MariaDB, where one statement is run per call, the change is confined to the statement it is in. SQL Server and SQL Server Compact, where parameters are bound, are not affected. | ||||
| CVE-2026-126618 | 2026-11-11 | 5.3 Medium | ||
| The auto-ban of Progressive Robot hMailServer 6.0.0-B1 through 6.3.7 can be kept from banning an address after repeated failed logons, which allows a remote unauthenticated attacker who can connect from two or more addresses to go on guessing account passwords - over SMTP AUTH, IMAP and POP3, and over ManageSieve, CalDAV/CardDAV and the REST API where those are turned on (off by default) - without being banned. When the failed logons counted from one address reach MaxInvalidLogonAttempts (3 by default), the server clears that address's count, saves an IP range that refuses the address for AutoBanMinutes (60 by default) and drops the connection. The range is named "Auto-ban: " followed by the user name of the logon that reached the limit, and no two ranges may have the same name. The server chooses the name by checking candidates as written - the name, then the name with a number, a random suffix or a GUID added - and only then cuts it to the 100 characters the database column holds, so that with a user name of 90 characters or more every candidate is the same once cut. While one range named after such a user name stands, every later ban named after a user name with the same first 90 characters therefore fails at the database: no range is saved, the address is not refused, and, its count having already been cleared, it is given the next full set of attempts. A user name of 78 to 89 characters makes later bans fail in the same way: from the second, the third or the twelfth on, depending on its length and the database, or, from 78 to 85 characters, by chance. An attacker who has once had an address banned under such a name can in this way keep guessing passwords from any other address, ending each set of attempts with a logon under a name of that kind; each failed save is reported in the server's error log (as the database error HM5032, and from 6.2.19 also as HM6099). On SQL Server a user name holding characters outside the database's code page has the same effect at any length, because the check compared names in that code page; that save is refused by the server's own check of the name, with no database error, and is reported only from 6.2.19 (HM6099). A user name holding a NUL character, which the web services listener's HTTP Basic sign-in (off by default) carries from 6.3.3 and, on the Linux builds, IMAP LOGIN, offered as installed, from 6.3.0, makes bans fail at any length: on MySQL, MariaDB and PostgreSQL the statements that check the name and save the range end at the character, so that every ban named after such a name fails, from the first and from a single address, and, its count having already been cleared, the address is given the next full set of attempts; on SQL Server and SQL Server Compact the name is bound only as far as the character, so that while one range under the part before it stands, every later ban named after such a name fails. On SQL Server, and on MySQL and MariaDB for an account whose local part has nine characters or more, a guess at the account can itself carry a name of that kind, since those databases find an account under its address followed by spaces (and SQL Server also under one holding characters its comparison ignores), so that not even a MaxInvalidLogonAttempts of 1, which bans each failed logon under the name it gave, avoids it there. | ||||
| CVE-2026-126616 | 2026-11-11 | 5.3 Medium | ||
| The auto-ban of Progressive Robot hMailServer 6.2.0 through 6.3.3, with a MySQL or MariaDB database, can be kept from banning an address after repeated failed logons, which allows a remote unauthenticated attacker to go on guessing account passwords from a single address without being banned. The server makes its MySQL tables in MySQL's utf8 character set, which holds no character outside the Basic Multilingual Plane, sends its statements as UTF-8 over a utf8mb4 connection and leaves the database's default strict mode in place. From 6.2.0 it decodes the user name of a SASL PLAIN logon as UTF-8, so the name can hold such a character. When the failed logons counted from one address reach MaxInvalidLogonAttempts (3 by default), the server clears that address's count, saves an IP range named "Auto-ban: " followed by the user name of the logon that reached the limit, and drops the connection. If such a character is in the part of the user name that the range's name keeps (the name is cut to 100 characters), the database refuses the range: no range is saved, the address is not refused, and, its count having already been cleared, it is given the next full set of attempts. An attacker can in this way spend all but the last attempt of each set on password guesses, and make the last under such a name. On Windows, POP3 AUTH PLAIN reaches it on a server as installed, and IMAP AUTHENTICATE PLAIN where IMAP SASL authentication is turned on (off by default); on Windows and on Linux (from 6.3.0), SMTP AUTH PLAIN reaches it where plain-text authentication is allowed (off by default), and ManageSieve and CardDAV where they are turned on (off by default). Each failed save is reported in the server's error log. A database whose strict mode has been turned off stores the character as a question mark and makes the first such ban, but refuses every later ban named after the same user name, or after one holding other such characters in their place, as a duplicate while the first stands, since the server cannot look up a name holding such a character there. | ||||
| CVE-2026-126615 | 2026-11-11 | 5.3 Medium | ||
| The sign-in of Progressive Robot hMailServer 6.2.22-pre2 through 6.3.7 takes for an account names that are not its address but under which the database's own comparison finds it, while the per-name lockout and the compromised-account hold are kept by the name as the client gave it. This allows a remote unauthenticated attacker to go on guessing an account's password beyond the lockout's threshold, and anyone who has the password of an account held for review to sign in to it. The per-name lockout (from 6.2.22-pre2; AccountLockoutThreshold in hMailServer.ini, 0, off, by default) locks a name after repeated failed sign-ins. The hold (from 6.3.4, where the compromised-account detection is set to enforce, which is not the default) refuses an account judged to have been taken over. Both are asked, before the password, of the name the client gave: trimmed, in lower case and with a domain alias or the default domain applied. The account whose password the sign-in then checks is whichever one the database finds under that name. The databases find an account under spellings that this key counts apart. MySQL and MariaDB find it under one with accented letters in place of plain ones, and MariaDB 11.8, in a database made before 6.3.4, also under one with full-width letters, with a single letter in place of a pair of plain ones, or with characters its comparison ignores in any number. SQL Server and SQL Server Compact find it under one with full-width letters or with characters their comparison ignores in any number, and SQL Server also under one with a single letter in place of a pair of plain ones, with a character of Latin-1 in place of a digit and, for an address holding letters of Latin-1 outside ASCII, under those letters in the other case, and, under an accent-insensitive collation, with accented letters. PostgreSQL finds it under one holding a letter whose lower case under the database's locale is a plain letter, and, for an address holding letters outside ASCII, under those letters in the other case; on the build for musl (from 6.3.6) the server's own lower case folds nearly all of these too. On every database, a domain alias saved with white space at the end of its name gives such a spelling too, and on every database but PostgreSQL so does an account's bare local part where the default domain was saved with spaces at its end and no other white space (neither is the default). Each such spelling has a lockout threshold of its own, so the lockout limits the guesses at an account only to its threshold times the number of the account's spellings. That is far beyond any threshold for most addresses on MySQL and MariaDB, and without limit on SQL Server, on SQL Server Compact, the database the Windows installer uses by default, and before 6.3.4 on MariaDB 11.8. A locked name is got round under another spelling. A held account is signed in to under another spelling with its password over IMAP, POP3 and SMTP AUTH, and, where they are turned on (off by default), over ManageSieve, the REST API and the webmail. IMAP LOGIN, offered as installed, carries such spellings on MySQL, MariaDB and SQL Server Compact, and, on SQL Server and PostgreSQL, for some addresses; the sign-ins that carry a name as UTF-8 carry them for the others on SQL Server, and on PostgreSQL for those holding one of the plain letters another letter lowers to or a letter outside ASCII with another case. The same lookup mapped to accounts the names given by an OAuth 2.0 token, a client certificate, a Kerberos ticket and an OpenID Connect or SAML identity provider, where those are set up (none is by default), so that a name an issuer gave to one party could sign in to another's account; OAuth 2.0 tokens were mapped so from 6.2.0, before the per-name lockout existed. A name holding a NUL character, carried from 6.3.0 on Linux and 6.3.3 on Windows, failed the statement on MySQL, MariaDB and PostgreSQL. | ||||
