Summary

The Calculated Fields Form plugin for WordPress prior to version 1.1.151 has a vulnerability that arises from its failure to properly sanitize and escape certain form settings. This weakness allows users with high privileges, including administrators, to conduct Stored Cross-Site Scripting (XSS) attacks. This issue can occur even in environments where the unfiltered_html capability is intentionally disabled, such as multisite installations, thereby posing a significant risk to the security of WordPress websites.
