------------------------------------------------------------------------- Debian LTS Advisory DLA-4564-1 [email protected] https://www.debian.org/lts/security/ Jochen Sprickerhof May 05, 2026 https://wiki.debian.org/LTS -------------------------------------------------------------------------
Package : pyjwt Version : 1.7.1-2+deb11u1 CVE ID : CVE-2026-32597 It was discovered that PyJWT, a Python implementation of JSON Web Token did not validate the crit (Critical) Header Parameter defined in RFC 7515 ยง4.1.11. 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 violates the MUST requirement in the RFC. For Debian 11 bullseye, this problem has been fixed in version 1.7.1-2+deb11u1. We recommend that you upgrade your pyjwt packages. For the detailed security status of pyjwt please refer to its security tracker page at: https://security-tracker.debian.org/tracker/pyjwt Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS
