{"id":"CVE-2026-10752","kind":"vulnerability","aliases":["CVE-2026-10752"],"related":[],"title":"WordPress ACF Extended plugin lets anonymous visitors delete media attachments","description":"The Advanced Custom Fields: Extended plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 0.9.2.6. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to permanently delete arbitrary WordPress media library attachments by supplying a numeric attachment ID in the form submission without any ownership or capability verification. Exploitation requires a site administrator to have configured a public-facing ACFE form with an Email action whose attachment row uses a dynamic {field:...} source bound to a submittable field with the Delete option enabled.","summary":"The Advanced Custom Fields: Extended plugin for WordPress up to and including 0.9.2.6 does not check authorization when a form submits an attachment ID.
