Users should monitor the vendor advisory for updates. Until a fix is available, restrict user roles and capabilities to minimize exposure. Implement additional access controls or input validation as a temporary mitigation.
Description
Mapster WP Maps plugin for WordPress versions up to and including 1.23.0 contains an improper input validation vulnerability in the my_profile_update() function. This flaw allows authenticated users with Subscriber-level access or higher to update arbitrary user meta values without nonce verification, capability checks, or allowlist validation. Although this can lead to modification of user metadata, privilege escalation is not possible. The vulnerability has a high severity score of 8.8 CVSS 3.1.
