No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The Crawlomatic Multipage Scraper Post Generator plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.7.2 via the filter_content function. This is due to passing the attacker-supplied 'callback_raw' shortcode attribute directly into call_user_func() with no sanitization or allowlist validation, relying solely on an is_callable() check that permits dangerous PHP built-ins such as system, shell_exec, exec, passthru, and assert. This makes it possible for authenticated attackers, with author-level access and above, to execute code on the server. An identical sink exists for the 'callback' attribute, providing a second independent vector through the same shortcode.
