| 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. |
| The Fedora Secure Boot CA certificate shipped with shim in Fedora was expired which could lead to old or invalid signed boot components being loaded. |
| sigstore-python is a Python tool for generating and verifying Sigstore signatures. Versions of sigstore-python newer than 2.0.0 but prior to 3.6.0 perform insufficient validation of the "integration time" present in "v2" and "v3" bundles during the verification flow: the "integration time" is verified *if* a source of signed time (such as an inclusion promise) is present, but is otherwise trusted if no source of signed time is present. This does not affect "v1" bundles, as the "v1" bundle format always requires an inclusion promise.
Sigstore uses signed time to support verification of signatures made against short-lived signing keys. The impact and severity of this weakness is *low*, as Sigstore contains multiple other enforcing components that prevent an attacker who modifies the integration timestamp within a bundle from impersonating a valid signature. In particular, an attacker who modifies the integration timestamp can induce a Denial of Service, but in no different manner than already possible with bundle access (e.g. modifying the signature itself such that it fails to verify). Separately, an attacker could upload a *new* entry to the transparency service, and substitute their new entry's time. However, this would still be rejected at validation time, as the new entry's (valid) signed time would be outside the validity window of the original signing certificate and would nonetheless render the attacker auditable. |
| ### 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.

| A vulnerability has been identified in APOGEE PXC Series (BACnet) (All versions), APOGEE PXC Series (P2 Ethernet) (All versions), TALON TC Series (BACnet) (All versions). Affected devices contain a weak encryption mechanism based on a hard-coded key.
This could allow an attacker to guess or decrypt the password from the cyphertext. |
| An issue in the index.js decryptCookie function of cookie-encrypter v1.0.1 allows attackers to execute a bit flipping attack. |
| Use of Hard-coded Cryptographic Key vulnerability in ABB RMC-100, ABB RMC-100 LITE.
An attacker can gain access to salted information to decrypt MQTT information.
This issue affects RMC-100: from 2105457-043 through 2105457-045; RMC-100 LITE: from 2106229-015 through 2106229-016. |
| Use of hard-coded cryptographic key issue exists in "Kura Sushi Official App Produced by EPARK" for Android versions prior to 3.8.5. If this vulnerability is exploited, a local attacker may obtain the login ID and password for the affected product. |
| Pheonix App is a Python application designed to streamline various tasks, from managing files to playing mini-games. The issue is that the map of encoding/decoding languages are visible in code. The Problem was patched in 0.2.4. |
| A vulnerability has been found in MartialBE one-hub up to 0.14.27. This vulnerability affects unknown code of the file docker-compose.yml. The manipulation of the argument SESSION_SECRET leads to use of hard-coded cryptographic key
. The attack may be initiated remotely. The complexity of an attack is rather high. It is stated that the exploitability is difficult. The exploit has been disclosed to the public and may be used. It is recommended to change the configuration settings. The code maintainer recommends (translated from Chinese): "The default docker-compose example file is not recommended for production use. If you intend to use it in production, please carefully check and modify every configuration and environment variable yourself!" |
| desknet's NEO V4.0R1.0 to V9.0R2.0 contains a hard-coded cryptographic key, which allows an attacker to create malicious AppSuite applications. |
| The NXP Data Co-Processor (DCP) is a built-in hardware module for specific NXP SoCs¹ that implements a dedicated AES cryptographic engine for encryption/decryption operations. The dcp_tool reference implementation included in the repository selected the test key, regardless of its `-t` argument. This issue has been patched in commit 26a7. |
| The device is observed to accept deprecated TLS protocols, increasing the risk of cryptographic weaknesses. |
| The server supports at least one cipher suite which is on the NCSC-NL list of cipher suites to be phased out, increasing the risk of cryptographic weaknesses. |
| Reusing a nonce, key pair in encryption issue exists in "FreeFrom - the nostr client" App versions prior to 1.3.5 for Android and iOS. If this vulnerability is exploited, the content of direct messages (DMs) between users may be manipulated by a man-in-the-middle attack. |
| 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. |
| openwrt/asu is an image on demand server for OpenWrt based distributions. The request hashing mechanism truncates SHA-256 hashes to only 12 characters. This significantly reduces entropy, making it feasible for an attacker to generate collisions. By exploiting this, a previously built malicious image can be served in place of a legitimate one, allowing the attacker to "poison" the artifact cache and deliver compromised images to unsuspecting users. This can be combined with other attacks, such as a command injection in Imagebuilder that allows malicious users to inject arbitrary commands into the build process, resulting in the production of malicious firmware images signed with the legitimate build key. This has been patched with 920c8a1. |
| Arcade MCP allows you to to create, deploy, and share MCP Servers. Prior to 1.5.4, the arcade-mcp HTTP server uses a hardcoded default worker secret ("dev") that is never validated or overridden during normal server startup. As a result, any unauthenticated attacker who knows this default key can forge valid JWTs and fully bypass the FastAPI authentication layer. This grants remote access to all worker endpoints—including tool enumeration and tool invocation—without credentials. This vulnerability is fixed in 1.5.4. |
| 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 |
