CVE-2026-8941: Wmark Cdn Linker Lite

Medium severity, CVSS 4.3. EPSS: 0.2% chance of exploitation in the next 30 days.

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.
