Prior to 1.3.1-stable and 1.3.9-beta, attacker-controlled path input is joined with a trusted base path prior to sanitization, allowing traversal sequences (e.g., ../) to escape the intended shared directory. As a result, an unauthenticated attacker possessing a valid public share hash with delete permissions enabled can delete arbitrary files outside the shared directory within the share owner’s configured storage scope. This affects public/api/resources and public/api/resources/bulk. This vulnerability is fixed in 1.3.1-stable and 1.3.9-beta.","state":0,"publishedAt":"2026-05-14T18:16:50.157+00:00","modifiedAt":"2026-10-25T23:10:00.167+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","score":9.1,"severity":"CRITICAL"}],"references":["https://github.com/gtsteffaniak/filebrowser/security/advisories/GHSA-fwj3-42wh-8673"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-44542","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-22"],"productCriteria":["cpe:2.3:a:gtsteffaniak:filebrowser_quantum:*:-:*:*:*:*:*:*","cpe:2.3:a:gtsteffaniak:filebrowser_quantum:*:beta:*:*:*:*:*:*"],"sourceDates":{"published":"2026-05-14T18:16:50.157","lastModified":"2026-10-25T23:10:00.167"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
