Summary

The WP Fastest Cache plugin for WordPress, prior to version 1.1.5, exposes a vulnerability due to the absence of a CSRF check in its AJAX actions. This oversight allows for potential exploitation by unauthenticated users. Additionally, the plugin fails to properly validate user input when utilizing the wp_remote_get() function, which could lead to a Blind Server-Side Request Forgery (SSRF) attack. This flaw can be leveraged to make unauthorized requests to internal or external systems, potentially exposing sensitive data and leading to further compromise.

Affected Version(s)

WP Fastest Cache 0 < 1.1.5

Exploit Proof of Concept (PoC)
