Technical details

A path traversal vulnerability exists in `view/update.php` due to insufficient sanitization of the `updateFile` POST parameter. The application concatenates this user-supplied input into a file path used by PHP's `file()` function during database migrations. An authenticated attacker with administrative privileges can use directory traversal sequences (e.g., `../../`) to bypass the intended `updatedb/` directory and read any text file reachable by the web server process, such as `/etc/passwd` or `.env` files. The vulnerability was verified on the master branch (commit bc03406) and affects versions up to and including 29.0.
