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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","score":9.1},"cwes":["CWE-22"],"references":["https://github.com/gtsteffaniak/filebrowser/security/advisories/GHSA-fwj3-42wh-8673","https://github.com/gtsteffaniak/filebrowser/security/advisories/GHSA-fwj3-42wh-8673"],"products":["gtsteffaniak:filebrowser_quantum"],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-44542","score":0.00523,"percentile":0.44082,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-fwj3-42wh-8673","url":"https://osv.dev/vulnerability/GHSA-fwj3-42wh-8673","summary":"FileBrowser Public Share DELETE API Path Traversal Allows Unauthenticated Arbitrary File Deletion","modified":"2026-06-25T19:56:38.896688055Z","packages":[{"ecosystem":"Go","name":"github.com/gtsteffaniak/filebrowser","purl":"pkg:golang/github.com/gtsteffaniak/filebrowser","ranges":["<0.0.0-20260501183844-112740bdd41d"],"fixed":["0.0.0-20260501183844-112740bdd41d"]}]},{"id":"GO-2026-5383","url":"https://osv.dev/vulnerability/GO-2026-5383","summary":"FileBrowser Public Share DELETE API Path Traversal Allows Unauthenticated Arbitrary File Deletion in github.com/gtsteffaniak/filebrowser","modified":"2026-06-25T19:45:36.745347388Z","packages":[{"ecosystem":"Go","name":"github.com/gtsteffaniak/filebrowser","purl":"pkg:golang/github.com/gtsteffaniak/filebrowser","ranges":["<0.0.0-20260501183844-112740bdd41d"],"fixed":["0.0.0-20260501183844-112740bdd41d"]}]}],"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).
