👾 Exploit Exists🟡 Public PoC

Summary

The WP Fastest Cache WordPress plugin prior to version 0.9.5 is prone to vulnerabilities due to the absence of a Cross-Site Request Forgery (CSRF) check in its wpfc_save_cdn_integration AJAX action. Additionally, the plugin does not properly sanitize and escape some options available through this action, enabling attackers to compel authenticated users with high privileges to execute this action and potentially set a Cross-Site Scripting payload. This flaw poses a risk to the security integrity of websites utilizing the plugin, highlighting the need for users to upgrade to the latest version to mitigate potential exploits.

Affected Version(s)

WP Fastest Cache 0 < 0.9.5

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.
