{"id":"CVE-2026-54096","aliases":["GHSA-3q2p-72cj-682c","GO-2026-5096"],"url":"https://o3.security/vulnerability/CVE-2026-54096","summary":"File Browser: Improper Access Control Occurs via Pre-Created Public Share for a Non-existent Path","details":"File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.63.7, `POST /api/share/<path>` accepts an authenticated request for an arbitrary path and stores a public share record without checking whether the target file currently exists. Later, when a file is created at that same path, the previously created public share immediately becomes valid and exposes the new file through `GET /api/public/dl/<hash>`. This vulnerability is fixed in 2.63.7.","published":"2026-06-25T17:35:02.206Z","modified":"2026-08-07T11:31:09.044171332Z","cvss":{"score":8.4,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser/v2","fixedVersion":"2.63.7"},{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54096.json"},{"type":"ADVISORY","url":"https://github.com/filebrowser/filebrowser/security/advisories/GHSA-3q2p-72cj-682c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54096"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:09.044171332Z"}}
