What the vulnerability does
01Description
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.
