UBUNTU-CVE-2026-39373

JWCrypto implements JWK, JWS, and JWE specifications using python-cryptography. Prior to 1.5.7, an unauthenticated attacker can exhaust server memory by sending crafted JWE tokens with ZIP compression. The existing patch for CVE-2024-28102 limits input token size to 250KB but does not validate th...

PYSEC-2026-120

PyJWT is a JSON Web Token implementation in Python. Prior to 2.12.0, PyJWT does not validate the crit Critical Header Parameter defined in RFC 7515 §4.1.11. When a JWS token contains a crit array listing extensions that PyJWT does not understand, the library accepts the token instead of rejecting...

go-jose: Go JOSE's Parsing Vulnerable to Denial of Service

A flaw was found in GO-JOSE. In affected versions, when parsing compact JWS or JWE input, Go JOSE could use excessive memory. The code uses strings.Splittoken, "." to split JWT tokens, which is vulnerable to excessive memory consumption when processing maliciously crafted tokens with a large numb...

namshi/jose insecure JSON Web Signatures (JWS)

namshi/jose allows the acceptance of unsecure JSON Web Signatures JWS by default. The vulnerability arises from the $allowUnsecure flag, which, when set to true during the loading of JWSes, permits tokens signed with 'none' algorithms to be processed. This behavior poses a significant security ri...
