{"id":"CVE-2020-5222","aliases":["GHSA-mh8g-hprg-8363"],"url":"https://o3.security/vulnerability/CVE-2020-5222","summary":"Hard-Coded Key Used For Remember-me Token in Opencast","details":"Opencast before 7.6 and 8.1 enables a remember-me cookie based on a hash created from the username, password, and an additional system key. This means that an attacker getting access to a remember-me token for one server can get access to all servers which allow log-in using the same credentials without ever needing the credentials. This problem is fixed in Opencast 7.6 and Opencast 8.1","published":"2020-01-30T21:15:14.980Z","modified":"2026-07-09T01:25:40.869908Z","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":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.opencastproject:opencast-kernel","fixedVersion":"7.6"},{"ecosystem":"Maven","name":"org.opencastproject:opencast-kernel","fixedVersion":"8.1"}],"fix":{"url":"https://github.com/opencast/opencast/commit/1a7172c95af8d542a77ae5b153e4c834dd4788a6","label":"opencast/opencast@1a7172c"},"references":[{"type":"ADVISORY","url":"https://github.com/opencast/opencast/security/advisories/GHSA-mh8g-hprg-8363"},{"type":"FIX","url":"https://github.com/opencast/opencast/commit/1a7172c95af8d542a77ae5b153e4c834dd4788a6"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T01:25:40.869908Z"}}
