Name of the Vulnerable Software and Affected Versions Monstra CMS versions prior to 3.0.5

Recommendations For Monstra CMS versions prior to 3.0.5, update to version 3.0.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the edit URI for user accounts to minimize the risk of exploitation.
