Overview
Affected versions of this package are vulnerable to UNIX Symbolic Link (Symlink) Following via the WebDAV backend process. An attacker can access and modify files outside the intended directory by exploiting symbolic links that point outside the designated root. This is only exploitable if a symbolic link already exists within the shared directory that points outside the root, as the attacker cannot create such links remotely.
