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":"2026-05-14T17:07:30.602+00:00","modifiedAt":"2026-05-15T15:03:11.944+00:00","affected":[{"ecosystem":"Vendor product","name":"filebrowser","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"gtsteffaniak\",\n                    \"product\": \"filebrowser\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.3.1-stable\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"< 1.3.9-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:N/I:H/A:H","score":9.1,"severity":"CRITICAL"}],"references":["https://github.com/gtsteffaniak/filebrowser/security/advisories/GHSA-fwj3-42wh-8673"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-44542","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-44542","identifiers":["CVE-2026-44542"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
