From 2.9.0 until 2.14.0, PyJWKSet does not catch the plain ValueError raised for malformed RSA JWK components by RSAAlgorithm.from_jwk in jwt/api_jwk.py. This occurs when a JWK Set contains a malformed RSA key alongside otherwise usable keys. As a result, one malformed member aborts construction of the entire PyJWKSet. Consequently, applications can experience authentication failures or request-level denial of service. This issue is fixed in version 2.14.0.","evidence":"cve:CVE-2026-102274","products":[{"name":{"value":"pyjwt","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"medium","structured":{"id":"CVE-2026-102274","aliases":["CVE-2026-102274"],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":5.9,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"HIGH","availabilityImpact":"HIGH","privilegesRequired":"NONE","confidentialityImpact":"NONE"}}],"affected":[{"vendor":"jpadilla","product":"pyjwt","versions":[{"status":"affected","version":">= 2.9.0, < 2.14.0"}]}],"modified":"2026-09-29T19:38:02.520Z","provider":"cve","references":["https://github.com/jpadilla/pyjwt/security/advisories/GHSA-w6j9-cwv2-h6wq","https://github.com/jpadilla/pyjwt/commit/8915570a0bfda9f0ff0e34e7fb09bdb9d71580cf","https://github.com/jpadilla/pyjwt/releases/tag/2.14.0"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-102274","role":"CISA Coordinator","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-29T19:37:35.694440Z"}}}],"references":[{"url":"https://github.com/jpadilla/pyjwt/security/advisories/GHSA-w6j9-cwv2-h6wq","tags":["exploit"]}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-29T19:38:02.520Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-09-28T20:42:28.355Z"}}},"related_cves":[{"value":"CVE-2026-102274","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":3972,"next_before":3972}
