cvss score 6.4
cwe CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
published Oct 6, 2025
The Cornerstone plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 7.7.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
