CVE-2026-8941 (GCVE-0-2026-8941)

Vulnerability from cvelistv5 – Published: 2026-05-27 05:31 – Updated: 2026-05-27 10:37

Title

CDN Linker lite <= 1.3.1 - Cross-Site Request Forgery to Plugin Settings Update

Summary

The CDN Linker lite plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.3.1. This is due to missing or incorrect nonce validation on the ossdl_off_options() function. This makes it possible for unauthenticated attackers to update the plugin's settings — including the CDN URL used to rewrite all static asset references on the site — via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
