BM Content Builder < 3.17.1 - Authenticated (Subscriber+) Arbitrary File Deletion

8.8
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVE CVE-2025-1281
CVSS 8.8 (High)
Publicly Published September 21, 2026
Last Updated September 22, 2026
Researcher Tonn

Description

The BM Content Builder plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the ux_cb_remove_layout_ajax() and ux_cb_tools_export_ajax() functions in all versions up to, and excluding, 3.17.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).
