{"id":"CVE-2026-41133","aliases":["GHSA-66hx-chf7-3332","PYSEC-2026-2990"],"url":"https://o3.security/vulnerability/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.","published":"2026-04-21T23:41:06.258Z","modified":"2026-07-15T01:48:53.475045465Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.00325,"percentile":0.2497,"asOf":"2026-08-05"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"pyload-ng","fixedVersion":null}],"fix":{"url":"https://github.com/pyload/pyload/commit/e95804fb0d06cbb07d2ba380fc494d9ff89b68c1","label":"pyload/pyload@e95804f"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:48:53.475045465Z"}}
