PHP Webshell Campaign Targets WordPress Through Critical WooCommerce Plugin Bug

Wordfence blocked over 100,000 exploitation attempts against CVE-2026-27540 in WooCommerce Wholesale Lead Capture, letting attackers upload PHP webshells to WordPress sites.

Wordfence reported more than 100,000 blocked exploitation attempts against CVE-2026-27540 in the WooCommerce Wholesale Lead Capture plugin (roughly 6,000 active installs), which was disclosed and patched on February 20 in version 2.0.3.2. The unauthenticated AJAX handler wwlc_file_upload_handler reads permitted file extensions from the attacker-controlled request, enabling arbitrary file upload of PHP files such as shell.php that report host details and serve further upload forms.
