Prior to 2.18.19 and from 2.19.0-alpha3 until 2.19.5-beta5, ProjectMiddleware and GetProjectOrGlobalRoleBySlug allow a project manager to use POST /api/project/{id}/roles to create a custom manager role with permission bitmask 15, overriding the built-in manager permissions and granting CanUpdateProject and CanManageProjectUsers owner capabilities. This issue is fixed in versions 2.18.19 and 2.19.5-beta5.","published":"2026-08-12T16:17:22.493","modified":"2026-08-12T16:17:22.493","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":null,"affectedPackages":[],"fix":{"url":"https://github.com/semaphoreui/semaphore/commit/1c4bb65df114962134f8829d4a03667106a01a68","label":"semaphoreui/semaphore@1c4bb65"},"references":[{"type":"WEB","url":"https://github.com/semaphoreui/semaphore/commit/1c4bb65df114962134f8829d4a03667106a01a68"},{"type":"WEB","url":"https://github.com/semaphoreui/semaphore/commit/bb2a4e1f08c8023e618f8dd6eaca73554f2c33bb"},{"type":"WEB","url":"https://github.com/semaphoreui/semaphore/releases/tag/v2.18.19"},{"type":"WEB","url":"https://github.com/semaphoreui/semaphore/releases/tag/v2.19.5-beta5"},{"type":"WEB","url":"https://github.com/semaphoreui/semaphore/security/advisories/GHSA-cxvf-gvfq-36w2"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T16:17:22.493"}}
