Overview

CVE-2026-9187 is a medium-severity vulnerability. It was published on June 16, 2026 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The Abandoned Contact Form 7 plugin for WordPress is vulnerable to unauthorized arbitrary post deletion in versions up to, and including, 2.2. This is due to a missing capability check and missing nonce validation in the action__remove_abandoned() function, which is registered to both the wp_ajax_remove_abandoned and wp_ajax_nopriv_remove_abandoned hooks. The handler takes a user-supplied recover_id parameter from $_POST and passes it directly to wp_delete_post() with the force-delete flag set to true, without verifying that the ID belongs to the plugin's own cf7af_data post type. This makes it possible for unauthenticated attackers to permanently delete arbitrary posts, pages, or other content on the affected site by sending a single admin-ajax.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
