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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-73293)\n\nAffected packages:\n\n- `github.com/semaphoreui/semaphore < 0.0.0-20260705182501-bb2a4e1f08c8`\n\nPatched in:\n\n- `github.com/semaphoreui/semaphore 0.0.0-20260705182501-bb2a4e1f08c8`\n\nSource: https://github.com/advisories/GHSA-cxvf-gvfq-36w2","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
