The vulnerability affects WordPress's get_page_template() function for page-template resolution.

THE READ
What the cluster adds up to.
The recently discovered vulnerability in the get_page_template() function of WordPress is particularly concerning due to its potential for remote code execution (RCE) by unauthenticated attackers. This situation requires immediate attention from developers and system administrators who rely on WordPress for their websites.
To mitigate the risk, users must update their WordPress installations to the latest version promptly. The availability of backports for versions as old as 4.7 means that a significant number of sites can still secure themselves, although the update process may vary in complexity depending on the specific version in use.
It's important to note that while updates are available for WordPress, ClassicPress users are at a higher risk since no corresponding security update has been released. This discrepancy highlights the necessity for ClassicPress users to remain vigilant regarding their security practices and consider migrating to a supported platform if timely updates are not provided.
