CVE-2026-12995

Custom Field Template <= 2.7.8 - Authenticated (Contributor+) Insecure Direct Object Reference to Arbitrary Media File Deletion via 'file_field' Parameter

The Custom Field Template plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.7.8 via the edit_meta_value due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with contributor-level access and above, to delete arbitrary media attachments site-wide by supplying any numeric attachment ID in the file-field parameter alongside the corresponding delete flag, causing content loss and broken pages. Exploitation requires that the attacker's post is governed by a Custom Field Template containing at least one file-type field with the mediaRemove option not enabled, which is the default configuration for file fields.

Custom Field Template <= 2.7.8 - Authenticated (Contributor+) SQL Injection via 'post_ID' Parameter

The Custom Field Template plugin for WordPress is vulnerable to generic SQL Injection via the 'post_ID' parameter in all versions up to, and including, 2.7.8 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The capability check via current_user_can('edit_post', $id) is bypassable because WordPress internally casts $id to an integer for the permission evaluation while the full unsanitized string is preserved and passed to the SQL sink, and a valid nonce — which is also required — can be legitimately obtained by any Contributor-level user from the post edit screen.
