PyJWT: Unauthenticated RecursionError DoS in pre-verification payload parse (PyJWKClient.get_signing_key_from_jwt / verify_signature=False)
Summary PyJWKClient.getsigningkeyfromjwttoken — the first step of the JWKS verification flow documented in docs/usage.rst — must decode a token's payload before its signature can be checked, via jwt.apijwt.decodecompletetoken, options="verifysignature": False. That call parses the payload with...

CVE-2026-102265
PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, PyJWS.load in jwt/apijws.py is affected because parser catches ValueError but not RecursionError. This occurs when a deeply nested token header reaches json.loads. As a result, RecursionError escapes the...

CVE-2026-102265 PyJWT: Uncaught RecursionError in jwt.decode() on deeply nested token header
PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, PyJWS.load in jwt/apijws.py is affected because parser catches ValueError but not RecursionError. This occurs when a deeply nested token header reaches json.loads. As a result, RecursionError escapes the...
CVE-2026-102265
The PyJWT Python library (versions 2.13.0 through 2.13.x ) is vulnerable due to a missing exception handler in the PyJWS._load function within jwt/api_jws.py. The parser currently catches ValueError but fails to catch RecursionError, which can be triggered when processing a deeply nested token he...

CVE-2026-101918
The PyJWT library (versions 2.0.0a1 to 2.15.0 ) contains a vulnerability in PyJWKClient.get_signing_key_from_jwt when verify_signature=False . The root cause is that the payload parser catches ValueError but fails to handle RecursionError during json.loads when processing an attacker-controlled, ...
