CVE-2026-75018

The Custom Contact Forms plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 7.16. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to permanently force-delete arbitrary posts of any post type (including pages, administrator-authored posts, and WooCommerce products) and write arbitrary ccf field * post meta onto any post regardless of ownership or post type. The top-level form ID is checked via edit post/publish posts, but the nested fields[].ID and choices[].ID paths processed by create and map fields() and create and map choices() carry no equivalent capability or post-type guard, leaving those sinks fully exposed while delete item() and delete submission() contain explicit post-type restriction fixes demonstrating the developer's awareness of scoping requirements.
