CVE-2021-34637

Name of the Vulnerable Software and Affected Versions: The Post Index WordPress plugin versions up to and including 0.7.5

Description: The issue allows attackers to inject arbitrary web scripts via Cross-Site Request Forgery, specifically through the OptionsPage function found in the ~/php/settings.php file. This enables attackers to execute malicious actions on the affected system.

Recommendations: For versions up to and including 0.7.5, update to a version later than 0.7.5 to resolve the issue. As a temporary workaround, consider restricting access to the OptionsPage function in the ~/php/settings.php file until a patch is available.
