Important: python-jwt

Issue Overview: PyJWT is a JSON Web Token implementation in Python. Prior to 2.13.0, when the verifier is decoding JSON Web Tokens, while supporting both asymmetric and HMAC algorithms, the library does not validate use of JSON Web Keys in HMAC algorithm, allowing attacker to use the issuer publi...

python-pyjwt: PyJWT: Authentication bypass due to forged JSON Web Tokens

A flaw was found in PyJWT, a Python library for JSON Web Token JWT implementation. When decoding JWTs, the library fails to validate the use of JSON Web Keys JWK in the HMAC algorithm while also supporting asymmetric algorithms. This allows a remote attacker to use the issuer's public key as the...

CVE-2026-48522

A flaw was found in PyJWT, a JSON Web Token implementation in Python. The PyJWKClient component, prior to version 2.13.0, directly passes its Uniform Resource Identifier URI argument to urllib.request.urlopen. This allows a remote attacker, by influencing the application's jku URL ingestion path,...

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-2026-48524

PyJWT is a JSON Web Token implementation in Python. Prior to 2.13.0, PyJWKClient.getsigningkey forces a fresh HTTP request to the JWKS endpoint for every JWT with an unknown kid value, with no rate limiting. Since kid comes from the unverified token header, an attacker can trigger unlimited...

CVE-2026-48526

PyJWT (Python) prior to 2.13.0 did not validate the use of JSON Web Keys in HMAC verification, allowing an attacker to use the issuer public key as the HMAC secret during token verification. This could enable forging tokens when mixing RS/EC/JWK and HS algorithms. The issue is fixed in PyJWT 2.13...
