Linux Distros Unpatched Vulnerability : CVE-2026-48525

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - PyJWT is a JSON Web Token implementation in Python. From 2.8.0 to 2.12.1, when verifying detached JWS tokens using the unencoded-payload option b64: false, RFC...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the Base64URL decoding process. An attacker can cause excessive CPU and memory consumption by supplying an arbitrarily large payload segment when verifying detached JWS tokens wit...

PYSEC-0000-CVE-2026-48525

PyJWT is a JSON Web Token implementation in Python. From 2.8.0 to 2.12.1, when verifying detached JWS tokens using the unencoded-payload option "b64": false, RFC 7797, PyJWT performs Base64URL decoding of the compact-serialization payload segment before enforcing the detached-payload rules. For...

CVE-2026-48525 PyJWT: Unauthenticated DoS via unbounded Base64URL decoding of unused payload segment in b64=false detached JWS

PyJWT is a JSON Web Token implementation in Python. From 2.8.0 to 2.12.1, when verifying detached JWS tokens using the unencoded-payload option "b64": false, RFC 7797, PyJWT performs Base64URL decoding of the compact-serialization payload segment before enforcing the detached-payload rules. For...

CVE-2026-48525

PyJWT (Python) versions 2.8.0–2.12.1 expose an unauthenticated DoS when verifying detached JWS with the unencoded-payload option (b64: false, RFC 7797). PyJWT decodes the middle payload segment for detached-payload verification, then discards it and replaces it with the caller-provided detached_p...

pyjwt: PyJWT accepts unknown `crit` header extensions (RFC 7515 §4.1.11 MUST violation)

A missing verification step has been discovered in PyJWT. 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 it. This...
