TencentOS Server 4: edk2 (TSSA-2026:0116)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0116 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities...

GHSA-7WC2-QXGW-G8GG Authlib: Setting `alg: none` and a blank signature appears to bypass signature verification

Summary After upgrading the library from 1.5.2 to 1.6.0 and the latest 1.6.5 it was noticed that previous tests involving passing a malicious JWT containing alg: none and an empty signature was passing the signature verification step without any changes to the application code when a failure was...

CVE-2025-15598

A vulnerability was found in Dataease SQLBot up to 1.5.1. This impacts the function validateEmbedded of the file backend/apps/system/middleware/auth.py of the component JWT Token Handler. Performing a manipulation results in improper verification of cryptographic signature. The attack can be...

RUSTSEC-2026-0077 Incorrect Check of Signer Response Norm During Verification

The ML-DSA verification algorithm as specified in FIPS 204, subsection 6.3 requires verifiers to check that the infinity norm of the deserialized signer response $z$ does not exceed $\gamma1 - \beta$ line 13 of Algorithm 8. The same check is required to be performed during signature generation...

RUSTSEC-2026-0075 All-Zero Key Generation on Catastrophic RNG Failure

The libcrux-ed25519 key generation samples Ed25519 secret keys from a provided CSPRNG in a loop for up to 100 attempts until a non-zero key is found. If a non-zero key could not be sampled within 100 attempts the key generation function would silently continue with an all-zero buffer as the secre...

RUSTSEC-2026-0076 Panic in Signature Hint Decoding During Verification

During ML-DSA verification the serialized hint values are decoded as specified in algorithm 22 HintBitUnpack of FIPS 204, subsection 7.1. The algorithm requires that the cumulative hint counters per row of the hint vector are strictly increasing and below a maximum value which depends on the choi...
