{"cve":"CVE-2026-41133","nvd":{"published":"2026-04-22T00:16:29.153","modified":"2026-06-17T10:46:12.737","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-613"],"references":["https://github.com/pyload/pyload/commit/e95804fb0d06cbb07d2ba380fc494d9ff89b68c1","https://github.com/pyload/pyload/security/advisories/GHSA-66hx-chf7-3332","https://github.com/pyload/pyload/security/advisories/GHSA-66hx-chf7-3332"],"products":["pyload:pyload"],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2026-41133","score":0.00325,"percentile":0.25623,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-66hx-chf7-3332","url":"https://osv.dev/vulnerability/GHSA-66hx-chf7-3332","summary":"pyLoad has Stale Session Privilege After Role/Permission Change (Privilege Revocation Bypass)","modified":"2026-07-13T16:42:54.687684300Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<=0.5.0b3.dev97"],"fixed":[]}]},{"id":"PYSEC-2026-2990","url":"https://osv.dev/vulnerability/PYSEC-2026-2990","summary":"pyLoad has Stale Session Privilege After Role/Permission Change (Privilege Revocation Bypass)","modified":"2026-07-13T16:32:35.333738024Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<=0.5.0b3.dev97"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
