What it detects

This rule detects inline PHP code appearing in a request URL, the code-injection technique used after CraftCMS CVE-2025-32432 exploitation to write a file manager webshell to the web root via file_put_contents and file_get_contents. Adversaries embed PHP tags and file functions in the request so the vulnerable application stores and executes attacker-controlled code.
