CVE-2026-3477

PZ Frontend Manager <= 1.0.6 - Missing Authorization to Arbitrary User Deletion via 'dataType' Parameter

Published Apr 8, 2026 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
The PZ Frontend Manager plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 1.0.6. The pzfm_user_request_action_callback() function, registered via the wp_ajax_pzfm_user_request_action action hook, lacks both capability checks and nonce verification. This function handles user activation, deactivation, and deletion operations. When the 'dataType' parameter is set to 'delete', the function calls wp_delete_user() on all provided user IDs without verifying that the current user has the appropriate permissions. Notably, the similar pzfm_remove_item_callback() function does check pzfm_can_delete_user() before performing deletions, indicating this was an oversight. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary WordPress users (including administrators) by sending a crafted request to the AJAX endpoint.

Analysis

AI-generated

Technical impact

The PZ Frontend Manager plugin has a missing authorization flaw in the pzfm_user_request_action_callback function. The function accepts an AJAX request with a 'dataType' parameter set to 'delete' and proceeds to call wp_delete_user on all supplied user IDs. Because it omits capability checks and nonce verification, any authenticated user with Subscriber role or higher can invoke the endpoint and delete arbitrary WordPress users, including administrators. This lowers system integrity and can lead to loss of legitimate user accounts and associated data.

Affected Systems

WordPress sites that run the PZ Frontend Manager plugin version 1.0.6 or earlier are affected. The plugin is distributed by projectzealous01 and serves as a frontend manager for WordPress sites.

Risk and Exploitability

The CVSS score of 5.3 indicates moderate severity. The EPSS score is not available, and the vulnerability is not listed in CISA’s KEV catalog. An authenticated attacker who can send a crafted AJAX request to the wp_ajax_pzfm_user_request_action endpoint can exploit the flaw. No additional external prerequisites are noted beyond a logged‑in session, and exploitation is straightforward once the attacker has a Subscriber level or higher account.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade PZ Frontend Manager to the latest release (≥1.0.7) which implements proper authorization checks for user deletion.
  • If an upgrade cannot be performed immediately, disable or uninstall the plugin until a patched version is available.
  • Restrict the permissions of lower user roles such as Subscriber, or remove the ability for subscribers to use the deletion feature by tightening role capabilities in WordPress.
