CVE-2026-102266 PyJWK accepts empty HMAC keys, bypassing PyJWT's empty-key validation

PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, HMACAlgorithm.fromjwk is affected because PyJWK verification path used the decoded key without applying preparekey validation. This occurs when a trusted JWK Set contains an oct entry with an empty k value. As...

CVE-2026-102266

The Python library PyJWT (versions 2.13.0 through 2.14.0 ) is vulnerable in the HMACAlgorithm.from_jwk function. The root cause is that the PyJWK verification path uses a decoded key without applying prepare_key validation when a trusted JWK Set contains an oct entry with an empty k value . This ...

openssl: PKCS#12 Files with PBMAC1 Are Accepted with Short HMAC Keys

A flaw was found in OpenSSL. This vulnerability allows a remote attacker to forge PKCS12 Public-Key Cryptography Standards 12 files that use Password-Based Message Authentication Code 1 PBMAC1 with short HMAC Hash-based Message Authentication Code keys. This can lead to a service accepting...

CVE-2026-49852

Summary: CVE-2026-49852 affects the Python library joserfc. Prior to version 1.6.8, joserfc.jwt.decode can accept attacker-forged HS256/HS384/HS512 tokens if the verification key is empty or None, enabling potential authentication bypass when the configured secret resolves to an empty string. The...
