CVE-2026-104107FileRise: Authenticated path traversal escapes configured storage root through inherited ACLs
Medium 6.5
In plain English
A medium-severity path traversal in FileRise from error311. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 30% of all known vulnerabilities).
Official description
FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. In FileRise 3.22.0, the /api/file/saveFile.php operation accepts dot and dot-dot segments in its attacker-controlled folder input before ACL inheritance evaluates the uncanonicalized string. With an authenticated non-administrator session, a valid CSRF token, and inherited edit permission on a legitimate ancestor, the local filesystem or WebDAV adapter later resolves those segments as path navigation, permitting attacker-controlled file creation outside the authorized folder and, where backend credentials permit, outside the configured WebDAV root. Local storage also created directories before final containment validation and used a prefix comparison that accepted similarly named sibling roots. This issue is fixed in version 3.23.0.
