AI-analyzed exploit summary This repository contains a functional Python script that exploits CVE-2026-11912, an unauthenticated file modification vulnerability in the Simple File List WordPress plugin. The script automates nonce extraction and brute-forces file operations, including path traversal to delete critical files like wp-config.php.

Description

The Simple File List plugin for WordPress is vulnerable to arbitrary file modification due to insufficient authorization checks in all versions up to, and including, 6.3.7. This makes it possible for unauthenticated attackers to delete and modify files on the serve. This vulnerability is exploitable even when the administrator has not enabled the AllowFrontManage setting, because the is_admin() check unconditionally short-circuits the guard before that setting is evaluated.
