{"id":"AZL-105230","summary":"CVE-2026-102265 affecting package python-jwt 2.13.0-1","details":"PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, PyJWS._load in jwt/api_jws.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 documented PyJWT error hierarchy. Consequently, an unauthenticated malformed token can cause a request-level failure and HTTP 500. This issue is fixed in version 2.14.0.","modified":"2026-10-01T14:15:53.955052779Z","published":"2026-09-28T21:17:14Z","upstream":["CVE-2026-102265"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102265"}],"affected":[{"package":{"name":"python-jwt","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/python-jwt"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.13.0-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-105230.json"}}],"schema_version":"1.9.0"}
