CVE-2026-33513: AVideo has an Unauthenticated Local File Inclusion in API locale (RCE possible with writable PHP)

An unauthenticated API endpoint (APIName=locale) concatenates user input into an include path with no canonicalization or whitelist. Path traversal is accepted, so arbitrary PHP files under the web root can be included. In our test this yielded confirmed file disclosure and code execution of existing PHP content (e.g., view/about.php), and it can escalate to RCE if an attacker can place or control a PHP file elsewhere in the tree.
