Summary

The Open User Map PRO plugin for WordPress up to version 1.4.31 is vulnerable to Stored Cross-Site Scripting via the 'oum_location_notification' parameter due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts that execute whenever a user accesses an injected page.

Risk Assessment

An attacker can inject a malicious script that executes in the browser of every visitor, potentially stealing session data, redirecting users, or performing other harmful actions.

Recommendation

Upgrade the Open User Map PRO plugin to a version later than 1.4.31.
