Description
HTMLy CMS through 3.1.1 contains a path traversal vulnerability that allows low-privileged authenticated attackers to relocate arbitrary files by supplying directory traversal sequences in the oldfile parameter at the admin autosave endpoint. Attackers can pass unsanitized traversal sequences directly to file_exists() and rename() functions in admin.php without canonicalization or directory boundary enforcement to cause unintended relocation of any file writable by the web server process to an attacker-specified draft location.
