What is CVE-2025-11171?

The Chartify plugin for WordPress has a security flaw whereby unauthenticated attackers can exploit an AJAX action without proper authentication or capability checks. This oversight allows malicious users to invoke administrative functions through the wp-admin/admin-ajax.php endpoint simply by knowing the callable method names. All versions up to and including 3.5.9 of the plugin are impacted, making it imperative for users to patch their installations to prevent unauthorized access.

Affected Version(s)

Chartify – WordPress Chart Plugin * <= 3.5.9

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
