CVE-2026-8941Network attack vector

Settings manipulation via missing nonce validation

Published May 27, 2026 · Updated May 27, 2026

Cross-site request forgery in CDN Linker lite 1.3.1 and earlier allows remote attackers to alter plugin settings via a forged request. The ossdl_off_options() function accepts settings submissions without validating a WordPress nonce, including the CDN URL that rewrites static asset references. Exploitation requires a logged-in site administrator to open the attacker-controlled request; the resulting configuration change can redirect static asset URLs.
