Exploit Blocked

What It Means

This request matches a known exploit pattern and was blocked by the WAF’s virtual patching or virtual hardening rules.

Why It Matters

Virtual patching blocks attacks that target known vulnerabilities in web frameworks, content management systems, and application platforms — even before you have applied the official software update. Virtual hardening applies broader protective rules that prevent exploitation of common application weaknesses. Together, they provide zero-day and known-vulnerability protection at the edge.

Common Triggers

Requests that match signatures for publicly disclosed vulnerabilities (CVEs) in popular frameworks like WordPress, Drupal, Rails, Django, or their plugins and extensions. These blocks often spike immediately after a new vulnerability is publicly disclosed, as attackers rush to exploit it across the internet.

What To Do

These blocks are critical protections. They stop real exploit attempts targeting known vulnerabilities. Do not create exceptions for these blocks unless you are absolutely certain the request is legitimate and the underlying vulnerability has been patched in your application.
