DescriptionCVE.org

The Kirki - Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation and missing capability check in the 'downloadZIP' function in all versions up to, and including, 6.0.6. This makes it possible for unauthenticated attackers to read and delete arbitrary files limited in the WordPress uploads base directory.

AnalysisAI

Arbitrary file read and deletion in the Kirki - Freeform Page Builder plugin for WordPress (versions through 6.0.6) allows unauthenticated remote attackers to read and delete files within the WordPress uploads base directory by abusing the 'downloadZIP' function. The flaw stems from insufficient path validation and a missing capability check, and was reported by Wordfence; no public exploit identified at time of analysis.

Technical ContextAI

Kirki is a popular WordPress customizer framework and page-builder plugin developed by Themeum. The vulnerable 'downloadZIP' function within includes/API.php is exposed without proper authorization (no current_user_can/capability check) and without sanitization of the requested file path, allowing relative path manipulation. This is a textbook CWE-23 (Relative Path Traversal) issue: user-supplied input is concatenated into a filesystem path used for both reading (zipping) and deleting files, with the WordPress uploads directory serving as the effective root, but with traversal possible within that scope.

RemediationAI

Upstream fix available (changeset 3535640 on the kirki trunk); released patched version not independently confirmed from the supplied data, so administrators should upgrade to the latest available Kirki release published after changeset 3535640 (any version greater than 6.0.6) via the WordPress plugin updater and verify the patched API.php is deployed. If immediate upgrade is not possible, compensating controls include deactivating the Kirki plugin entirely (trade-off: site customizer features and theme options may break), blocking unauthenticated requests to the plugin's REST/AJAX endpoints that reach the 'downloadZIP' handler at the web application firewall or via .htaccess/nginx rules (trade-off: may break legitimate customizer export functionality), and ensuring filesystem-level backups of wp-content/uploads exist so deleted files can be restored.
