CVE-2026-12100Network attack vector

Unauthenticated SSRF via unchecked URL fetch

Published Jun 24, 2026 · Updated Jun 24, 2026

SSRF in Abhishek Saha's URL Preview 1.0 and earlier allows remote attackers to send server-side requests via the url parameter. The public class.linkpreview.php endpoint passes the attacker-controlled value to its link-preview fetch routine without restricting the destination. No authentication is required, so an attacker can reach services accessible to the WordPress host and read or modify data exposed through their HTTP interfaces.
