| ### Impact
When this library is used to deserialize messagepack data from an untrusted source, there is a risk of a denial of service attack by an attacker that sends data contrived to produce hash collisions, leading to large CPU consumption disproportionate to the size of the data being deserialized.
This is similar to [a prior advisory](https://github.com/MessagePack-CSharp/MessagePack-CSharp/security/advisories/GHSA-7q36-4xx7-xcxf), which provided an inadequate fix for the hash collision part of the vulnerability.
### Patches
The following steps are required to mitigate this risk.
1. Upgrade to a version of the library where a fix is available.
1. Review the steps in [this previous advisory](https://github.com/MessagePack-CSharp/MessagePack-CSharp/security/advisories/GHSA-7q36-4xx7-xcxf) to ensure you have your application configured for untrusted data.
### Workarounds
If upgrading MessagePack to a patched version is not an option for you, you may apply a manual workaround as follows:
1. Declare a class that derives from `MessagePackSecurity`.
2. Override the `GetHashCollisionResistantEqualityComparer<T>` method to provide a collision-resistant hash function of your own and avoid calling `base.GetHashCollisionResistantEqualityComparer<T>()`.
3. Configure a `MessagePackSerializerOptions` with an instance of your derived type by calling `WithSecurity` on an existing options object.
4. Use your custom options object for all deserialization operations. This may be by setting the `MessagePackSerializer.DefaultOptions` static property, if you call methods that rely on this default property, and/or by passing in the options object explicitly to any `Deserialize` method.

| Missing cryptographic key commitment in the Amazon S3 Encryption Client for Go may allow a user with write access to the S3 bucket to introduce a new EDK that decrypts to different plaintext when the encrypted data key is stored in an "instruction file" instead of S3's metadata record.
To mitigate this issue, upgrade Amazon S3 Encryption Client for Go to version 4.0 or later. |
| Missing cryptographic key commitment in the AWS SDK for PHP may allow a user with write access to the S3 bucket to introduce a new EDK that decrypts to different plaintext when the encrypted data key is stored in an "instruction file" instead of S3's metadata record.
To mitigate this issue, upgrade AWS SDK for PHP to version 3.368.0 or later |
| Missing cryptographic key commitment in the AWS SDK for C++ may allow a user with write access to the S3 bucket to introduce a new EDK that decrypts to different plaintext when the encrypted data key is stored in an "instruction file" instead of S3's metadata record.

| CWE-328: Use of Weak Hash |
| The authentication process to the web server uses a challenge response procedure which
inludes the nonce and additional information. This challenge can be used several times for login and is
therefore vulnerable for a replay attack. |
| A low privileged local attacker can abuse the affected service by using a hardcoded cryptographic key. |
| Inadequate Encryption Strength vulnerability allow an authenticated attacker to execute arbitrary OS Commands via encrypted package upload.This issue affects Envoy: 4.x and 5.x |
| HCL DRYiCE Optibot Reset Station is impacted by insecure encryption of security questions. This could allow an attacker with access to the database to recover some or all encrypted values. |
| HCL DRYiCE Optibot Reset Station is impacted by insecure encryption of One-Time Passwords (OTPs). This could allow an attacker with access to the database to recover some or all encrypted values. |
| Inadequate encryption strength for some BMRA software before version 22.08 may allow an authenticated user to potentially enable escalation of privilege via local access. |
| This vulnerability exists in USB Pratirodh due to the usage of a weaker cryptographic algorithm (hash) SHA1 in user login component. A local attacker with administrative privileges could exploit this vulnerability to obtain the password of USB Pratirodh on the targeted system.
Successful exploitation of this vulnerability could allow the attacker to take control of the application and modify the access control of registered users or devices on the targeted system.

| A vulnerability was detected in PandaXGO PandaX up to fb8ff40f7ce5dfebdf66306c6d85625061faf7e5. This affects an unknown function of the file config.yml of the component JWT Secret Handler. The manipulation of the argument key results in use of hard-coded cryptographic key
. The attack may be performed from remote. This attack is characterized by high complexity. The exploitability is reported as difficult. The exploit is now public and may be used. This product utilizes a rolling release system for continuous delivery, and as such, version information for affected or updated releases is not disclosed. The project was informed of the problem early through an issue report but has not responded yet. |
| jose v6.0.10 was discovered to contain weak encryption. NOTE: this is disputed by a third party because the claim of "do not meet recommended security standards" does not reflect guidance in a final publication. |
| A vulnerability in the cryptographic logic used by HPE Aruba Networking EdgeConnect SD-WAN Gateways could allow an authenticated remote attacker to gain shell access. Successful exploitation could allow an attacker to execute arbitrary commands on the underlying operating system, potentially leading to unauthorized access and control over the affected systems. |
| Arris VIP1113 devices through 2025-05-30 with KreaTV SDK have a firmware decryption key of cd1c2d78f2cba1f73ca7e697b4a485f49a8a7d0c8b0fdc9f51ced50f2530668a. |
| LangChain4j-AIDeepin is a Retrieval enhancement generation (RAG) project. Prior to 3.5.0, LangChain4j-AIDeepin uses MD5 to hash files, which may cause file upload conflicts. This issue is fixed in 3.5.0. |
| A vulnerability in the SageMaker Workflow component of aws/sagemaker-python-sdk allows for the possibility of MD5 hash collisions in all versions. This can lead to workflows being inadvertently replaced due to the reuse of results from different configurations that produce the same MD5 hash. This issue can cause integrity problems within the pipeline, potentially leading to erroneous processing outcomes. |
| Agentflow developed by Flowring has an Use of Hard-coded Cryptographic Key vulnerability, allowing unauthenticated remote attackers to exploit the fixed key to generate verification information, thereby logging into the system as any user. Attacker must first obtain an user ID in order to exploit this vulnerability. |
| The Copypress Rest API plugin for WordPress is vulnerable to Remote Code Execution via copyreap_handle_image() Function in versions 1.1 to 1.2. The plugin falls back to a hard-coded JWT signing key when no secret is defined and does not restrict which file types can be fetched and saved as attachments. As a result, unauthenticated attackers can forge a valid token to gain elevated privileges and upload an arbitrary file (e.g. a PHP script) through the image handler, leading to remote code execution. |
