{"id":"AZL-104982","summary":"CVE-2026-101917 affecting package python-jwt 2.13.0-1","details":"PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, PyJWT get_signing_key_from_jwt is affected because unknown kid misses force refreshes without a negative cache or minimum refresh interval. This occurs when unauthenticated tokens repeatedly use the same unknown kid or varying kid values absent from the cached JWKS. As a result, each cache miss causes PyJWKClient to refresh the JWKS. Consequently, attacker traffic can amplify outbound requests to the configured JWKS endpoint. This issue is fixed in version 2.14.0.","modified":"2026-09-30T05:39:58Z","published":"2026-09-28T21:17:13Z","upstream":["CVE-2026-101917"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-101917"}],"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-104982.json"}}],"schema_version":"1.9.0"}
