{"id":"CVE-2026-41133","summary":"pyLoad has Stale Session Privilege After Role/Permission Change (Privilege Revocation Bypass)","details":"pyLoad is a free and open-source download manager written in Python. Versions up to and including 0.5.0b3.dev97 cache `role` and `permission` in the session at login and continues to authorize requests using these cached values, even after an admin changes the user's role/permissions in the database. As a result, an already logged-in user can keep old (revoked) privileges until logout/session expiry, enabling continued privileged actions. This is a core authorization/session-consistency issue and is not resolved by toggling an optional security feature. Commit e95804fb0d06cbb07d2ba380fc494d9ff89b68c1 contains a fix for the issue.","aliases":["GHSA-66hx-chf7-3332","PYSEC-2026-2990"],"modified":"2026-07-15T01:48:53.475045465Z","published":"2026-04-21T23:41:06.258Z","database_specific":{"unresolved_ranges":[{"extracted_events":[{"last_affected":"0.5.0b3.dev97"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"GitHub_M","cwe_ids":["CWE-613"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41133.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41133.json"},{"type":"ADVISORY","url":"https://github.com/pyload/pyload/security/advisories/GHSA-66hx-chf7-3332"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41133"},{"type":"FIX","url":"https://github.com/pyload/pyload/commit/e95804fb0d06cbb07d2ba380fc494d9ff89b68c1"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pyload/pyload","events":[{"introduced":"0"},{"fixed":"e95804fb0d06cbb07d2ba380fc494d9ff89b68c1"}],"database_specific":{"source":"REFERENCES"}}],"versions":["v0.4.9","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4","v0.3.2","v0.3.1","v0.3","v0.2.2","v0.2.1","v0.2","v0.1.1","v0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-41133.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
