Summary
Security update for python-PyJWT
Details

This update for python-PyJWT fixes the following issues

  • CVE-2026-48522: PyJWKClient passes URI arguments directly to urllib.request.urlopen() and allows for SSRF and token forgery (bsc#1266798).
  • CVE-2026-48523: verifier-side algorithm allow-list bypass when jwt.decode() or jwt.decode_complete() are called with a PyJWK key (bsc#1266799).
  • CVE-2026-48524: unlimited processing of JWTs with unknown kid values by PyJWKClient.get_signing_key() leads to unbounded JWKS endpoint requests and DoS (bsc#1266800).
  • CVE-2026-48525: unbounded Base64URL decoding of unused payload segment in b64=false detached JWS allows for DoS (bsc#1266801).
  • CVE-2026-48526: no validation of use of JSON Web Keys in HMAC algorithm when decoding JSON Web Tokens allows for forged HS256 tokens (bsc#1266802).
