Unauthenticated Recursion in WP Maps Pro Leading to DoS

Publication date: 2026-08-09

Last updated on: 2026-08-09

Assigner: WPScan

Description
The WP MAPS PRO WordPress plugin before 6.1.3 does not perform a capability check in one of its AJAX actions, which is also available to unauthenticated users, and does not restrict the operation it dispatches, allowing unauthenticated attackers to trigger uncontrolled recursion that exhausts server resources, resulting in a Denial of Service.

Executive Summary

This vulnerability affects the WP Maps Pro WordPress plugin versions before 6.1.3. It allows unauthenticated attackers to trigger uncontrolled recursion via an AJAX action that lacks capability checks, consuming server resources and causing a Denial of Service.

Detection Guidance

Check if the WP Maps Pro plugin version is below 6.1.3. Look for signs of high server resource usage or unresponsive services, which may indicate a DoS attack. Monitor server logs for unusual AJAX requests or recursion patterns.

Impact Analysis

If you use the WP Maps Pro plugin before version 6.1.3, attackers could exploit this flaw to exhaust your server resources, making your website unavailable. This could disrupt services and affect user access.

Compliance Impact

This vulnerability primarily causes a Denial of Service (DoS) by exhausting server resources through uncontrolled recursion. While it does not directly expose or leak data, a prolonged DoS could disrupt services handling sensitive data, potentially impacting compliance with GDPR (availability requirements) or HIPAA (operational integrity). However, the CVE does not provide specific details on data exposure or compliance violations.

Mitigation Strategies
  • Update the WP Maps Pro plugin to version 6.1.3 or later immediately.
  • Disable the plugin temporarily if an update is not immediately possible.
  • Restrict access to the vulnerable AJAX action via server-side rules if patching is delayed.
