Really Simple Security (Free) <= 9.8.2 - Unauthenticated Unbounded Option Growth
The Really Simple Security (Free) plugin for WordPress is vulnerable to Denial of Service in all versions up to, and including, 9.8.2. This is due to missing validation on client-supplied IP headers used as storage keys in the rsssl_404_cache option, allowing arbitrary values from HTTP_CLIENT_IP and HTTP_X_FORWARDED_FOR to be written as array keys without bound. This makes it possible for unauthenticated attackers to grow the rsssl_404_cache option without bound by supplying arbitrary values in spoofed client IP headers, degrading site performance when handling 404 responses.
