CVE-2026-2500
The Quick Playground plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.3.4. This is due to the qckply_data() function passing the user-supplied filename POST parameter directly to file_get_contents() without any validation, sanitization, or path restriction. This makes it possible for authenticated attackers, with Administrator-level access and above, to read arbitrary files on the server, such as wp-config.php or /etc/passwd, which can contain sensitive information.
Note: This vulnerability is only exploitable when the site has been synced with WordPress Playground (the is_qckply_clone option is set) or when running on playground.wordpress.net.
