Prior to version 1.3.2-beta, the `/api/auth/login` authentication endpoint does not execute in constant time. When a non-existent username is supplied, the server returns a `401`/`403` response almost immediately. When a valid username is provided, the server performs a bcrypt password comparison, causing a measurable delay in the response time. Version 1.3.2-beta patches the issue.","state":0,"publishedAt":"2026-07-20T14:17:13.083+00:00","modifiedAt":"2026-07-21T15:31:49.57+00:00","affected":[{"ecosystem":"Vendor product","name":"filebrowser","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"gtsteffaniak\",\n                    \"product\": \"filebrowser\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.3.2-beta\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/gtsteffaniak/filebrowser/security/advisories/GHSA-7789-65hx-f26w","https://github.com/gtsteffaniak/filebrowser/commit/af08800667b874620edc6f44c3e2e64fec7abd85","https://github.com/gtsteffaniak/filebrowser/releases/tag/v1.3.2-beta"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54685","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54685","identifiers":["CVE-2026-54685"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
