Summary
The Kirki plugin for WordPress up to version 6.1.1 is vulnerable to Directory Traversal via the 'data' parameter. Authenticated attackers with editor-level access and above can read arbitrary files on the server, including sensitive information, by bypassing the strpos()-based guard with traversal sequences in the URL.
Risk Assessment
Risk of disclosure of sensitive data such as configuration files with passwords or keys, potentially leading to full server compromise.
Recommendation
Update the Kirki plugin to the latest patched version. Restrict admin panel access to trusted users only.
Original NVD description (English source)
The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 6.1.1 via the 'data' parameter parameter. This makes it possible for authenticated attackers, with editor-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information. The intended strpos()-based guard against leaving the uploads directory is bypassed by crafting a URL that includes the uploads base path as a substring while embedding directory traversal sequences, such as /wp-content/uploads/../../wp-config.php.
