CVE-2026-13339: Path traversal vulnerability

The CubeWP Framework plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.1.30 via the 'cubewp_get_svg_content' function. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. This is exploitable by unauthenticated attackers because the required nonce is publicly emitted into the markup of any page rendering the CubeWP posts shortcode or widget with AJAX loading enabled, making it harvestable by any guest visitor before submitting the AJAX request.
