Attack-Flow Graph

Executive Summary

This vulnerability in the Eventin WordPress plugin before version 4.1.21 allows users with Contributor-level access or higher to modify other users' roles and metadata during speaker creation. The plugin fails to verify proper permissions before making these changes, enabling unauthorized role and metadata updates.

Detection Guidance

Check if the Eventin WordPress plugin version is below 4.1.21. Use WordPress admin panel to verify plugin versions or run commands like 'wp plugin list' in WP-CLI to inspect installed versions.

Impact Analysis

If you use the Eventin plugin with a vulnerable version, an attacker with Contributor access could escalate their privileges or alter other users' roles and metadata. This could lead to unauthorized access, data manipulation, or potential site compromise.

Compliance Impact

This vulnerability could impact compliance by allowing unauthorized role changes or metadata modifications, potentially violating access control requirements in GDPR or HIPAA. Unauthorized access or data changes may lead to regulatory penalties or breaches of confidentiality.

Mitigation Strategies

Update the Eventin plugin to version 4.1.21 or later immediately. Remove unnecessary user roles with contributor access or higher if not required. Monitor for unauthorized role changes or metadata updates.
