{"id":"CVE-2026-54096","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-54096","generatedAt":"2026-10-28T07:04:01.627Z","title":"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.","description":"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":"2026-06-25T19:16:42.000Z","lastModified":"2026-06-25T19:58:31.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","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"},"cwe":["CWE-863"],"affected":[],"epss":{"score":0.00182,"percentile":0.07699,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.18%).
