Summary
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. Unauthenticated attackers can read the contents of arbitrary files on the server, which can contain sensitive information. This is exploitable 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.
Risk Assessment
Attackers can access sensitive data such as configuration files, passwords, or API keys, potentially leading to further privilege escalation and compromise of the entire WordPress installation.
Recommendation
Update the CubeWP Framework plugin to the latest version that includes a fix for the directory traversal vulnerability.
Other vulnerabilities in CubeWP Framework
See all- CVE-2026-17018Medium
The CubeWP Framework WordPress plugin through version 1.1.30 does not perform a per-object read authorization check, nor restrict which metadata keys may be requested, on one of its REST API endpoints, allowing users with the Contributor role and above to read arbitrary post metadata (including that of other users' draft, pending, private, and password-protected posts) and arbitrary user metadata of any user, including administrators.
- CVE-2026-6453Medium
The CubeWP Framework plugin for WordPress is vulnerable to SQL injection in the `cubewp_remove_relation()` AJAX function. The use of `wp_unslash()` removes injection protection, and the lack of `$wpdb->prepare()` allows authenticated attackers with subscriber-level access to append additional SQL queries.
Original NVD description (English source)
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.
