Vulnerability Overview

The ImageRecycle pdf & image compression plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.1.14. This is due to missing or incorrect nonce validation on several functions in the class/class-image-otimizer.php file. This makes it possible for unauthenticated attackers to update plugin settings along with performing other actions via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in ImageRecycle pdf & image compression <= 3.1.14 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For ImageRecycle pdf & image compression the fix is 3.1.15: builds <= 3.1.14 are affected, anything from 3.1.15 onward is not.

Remediation

Update to version 3.1.15, or a newer patched version
