CVE-2026-13464: The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 6.0.14
The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 6.0.14 via the 'context' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to read the full title, content, and excerpt of any WordPress post — including drafts, pending, privately published, password-protected, and trashed posts — regardless of author, by supplying an arbitrary post ID via the context parameter alongside an attacker-controlled block template.
