Low risk13th percentile - higher than 13% of all known CVEs
Summary
The WP Maps WordPress plugin before 4.9.7 does not perform a capability check in one of its AJAX actions and does not restrict the operation it dispatches, allowing users with a Subscriber account to trigger uncontrolled recursion that exhausts server resources, resulting in a Denial of Service.
Risk Assessment
The risk is that a low-privileged user (Subscriber) can launch a DoS attack, potentially disrupting the WordPress site and affecting availability for all users.
Recommendation
Update the WP Maps plugin to version 4.9.7 or later, which includes the fix. Also consider restricting access to the AJAX action for unauthorized roles.
