A malicious actor can craft a forged token with arbitrary claims (e.g., is_admin=true) and bypass authentication checks, leading to privilege escalation or unauthorized access in applications that rely on python-jose for token validation. This issue is exploitable unless developers explicitly reject 'alg=none' tokens, which is not enforced by the library. NOTE: all parties agree that the issue is not relevant because it only occurs in a \"verify_signature\": False situation."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://pypi.org/project/python-jose"},{"url":"https://github.com/javiermorales36/PoC-for-python-jose-alg-none-JWT-bypass-vulnerability/blob/main/CVE-2025-61152_Security_Advisory.md"},{"url":"https://github.com/mpdavis/python-jose/issues/391"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}],"tags":["disputed"]},"adp":[{"problemTypes":[{"descriptions":[{"type":"CWE","cweId":"CWE-269","lang":"en","description":"CWE-269 Improper Privilege Management"}]}],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":6.5,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","integrityImpact":"LOW","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"NONE","confidentialityImpact":"LOW"}},{"other":{"type":"ssvc","content":{"timestamp":"2025-10-10T14:21:53.362493Z","id":"CVE-2025-61152","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-10-10T14:22:45.776Z"}}]},"dataVersion":"5.2"}
