{"cve":"CVE-2026-54685","nvd":{"published":"2026-07-20T15:16:43.787","modified":"2026-10-24T20:10:00.137","status":"Deferred","description":"FileBrowser Quantum is a free, self-hosted, web-based file manager. 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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-208"],"references":["https://github.com/gtsteffaniak/filebrowser/commit/af08800667b874620edc6f44c3e2e64fec7abd85","https://github.com/gtsteffaniak/filebrowser/releases/tag/v1.3.2-beta","https://github.com/gtsteffaniak/filebrowser/security/advisories/GHSA-7789-65hx-f26w","https://github.com/gtsteffaniak/filebrowser/security/advisories/GHSA-7789-65hx-f26w"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-54685","score":0.00338,"percentile":0.26944,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-7789-65hx-f26w","url":"https://osv.dev/vulnerability/GHSA-7789-65hx-f26w","summary":"FileBrowser Quantum has Username Enumeration via Authentication Timing Side-Channel","modified":"2026-07-08T17:56:10.957994202Z","packages":[{"ecosystem":"Go","name":"github.com/gtsteffaniak/filebrowser/backend","purl":"pkg:golang/github.com/gtsteffaniak/filebrowser/backend","ranges":["<0.0.0-20260317230626-af08800667b8"],"fixed":["0.0.0-20260317230626-af08800667b8"]}]},{"id":"GO-2026-4820","url":"https://osv.dev/vulnerability/GO-2026-4820","summary":"FileBrowser Quantum has Username Enumeration via Authentication Timing Side-Channel in github.com/gtsteffaniak/filebrowser/backend","modified":"2026-07-08T17:56:10.957994202Z","packages":[{"ecosystem":"Go","name":"github.com/gtsteffaniak/filebrowser/backend","purl":"pkg:golang/github.com/gtsteffaniak/filebrowser/backend","ranges":["<0.0.0-20260317230626-af08800667b8"],"fixed":["0.0.0-20260317230626-af08800667b8"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
