CVE-2026-107722 fast-jwt: Incomplete patch of CVE-2026-34950: Non-whitespace key-prefix re-enables RSA→HS256 algorithm confusion

fast-jwt provides fast JSON Web Token JWT implementation. From 6.2.0 until 6.3.0, fast-jwt can misclassify RSA public-key text as an HMAC secret when the key has non-whitespace content before its PEM header. In src/crypto.js, performDetectPublicKeyAlgorithms trims whitespace but publicKeyPemMatch...

CVE-2026-107722

The fast-jwt library (versions 6.2.0 to 6.3.0 ) is vulnerable to RSA→HS256 algorithm confusion due to an incomplete patch of CVE-2026-34950. The root cause resides in src/crypto.js, where performDetectPublicKeyAlgorithms trims whitespace but publicKeyPemMatcher remains start-anchored. This allows...

CVE-2026-98289

The Linux kernel contains a vulnerability in the af_unix component related to how Tarjan's algorithm handles SCC (Strongly Connected Component) indices. Specifically, the unix_vertex_dead() function assumes all vertices in an SCC share the same lowpoint (scc_index), but this assumption fails if a...

CVE-2026-85394

A flaw was found in python-jose. A remote attacker who obtains the service's public key can exploit an algorithm confusion vulnerability when signature verification algorithms are not strictly restricted. By utilizing a specifically formatted public key as a shared secret key, the attacker can...

Astra Linux – Vulnerability in Ceph

Ceph is a distributed object, block, and file storage platform. In versions 19.2.3 and earlier, it is possible to send a JWT with “none” as its JWT algorithm. By doing this, the JWT signature is not checked. The vulnerability lies most likely in the RadosGW OIDC provider. As of the time of...
