Prior to version 1.4.3-beta, the `subtitlesHandler` endpoint (`GET /api/media/subtitles`) accepts two user-controlled query parameters: `path` and `name`, both of which are used in filesystem operations without sanitization, creating two independent path traversal vectors. The primary vector is the `path` parameter: it is passed directly to `idx.GetRealPath()` without calling `SanitizeUserPath()`, allowing an attacker to escape the storage root and set `parentDir` to any directory on the host. No existing anchor file is required.  The secondary vector is the `name` parameter: it is joined with `parentDir` via `filepath.Join(parentDir, name)` without stripping directory components, allowing traversal relative to any resolved `parentDir`. Any authenticated user (regardless of role or permissions) can exploit either vector to read any text file readable by the server process, including `/etc/passwd`, SSH keys, database credentials, and JWT signing keys. Version 1.4.3-beta patches the issue.","state":0,"publishedAt":"2026-07-20T15:16:43.933+00:00","modifiedAt":"2026-10-24T20:10:00.137+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","score":7.7,"severity":"HIGH"}],"references":["https://github.com/gtsteffaniak/filebrowser/commit/f3f4bbe80cb569d664174aea874d7bfa008c3b5a","https://github.com/gtsteffaniak/filebrowser/security/advisories/GHSA-vvp7-h4fj-m28w"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-54910","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-22","CWE-23"],"productCriteria":[],"sourceDates":{"published":"2026-07-20T15:16:43.933","lastModified":"2026-10-24T20:10:00.137"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
