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.","state":0,"publishedAt":"2026-08-12T15:45:22.145+00:00","modifiedAt":"2026-08-12T16:56:45.324+00:00","affected":[{"ecosystem":"Vendor product","name":"semaphore","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"semaphoreui\",\n                    \"product\": \"semaphore\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.18.19\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.19.0-alpha3, < 2.19.5-beta5\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"HIGH"}],"references":["https://github.com/semaphoreui/semaphore/security/advisories/GHSA-cxvf-gvfq-36w2","https://github.com/semaphoreui/semaphore/commit/1c4bb65df114962134f8829d4a03667106a01a68","https://github.com/semaphoreui/semaphore/commit/bb2a4e1f08c8023e618f8dd6eaca73554f2c33bb","https://github.com/semaphoreui/semaphore/releases/tag/v2.18.19","https://github.com/semaphoreui/semaphore/releases/tag/v2.19.5-beta5"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-73293","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-73293","identifiers":["CVE-2026-73293"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
