CVE-2023-5205

Name of the Vulnerable Software and Affected Versions Add Custom Body Class plugin for WordPress versions up to, and including, 1.4.1

Description The issue is related to Stored Cross-Site Scripting via the add custom body class value due to insufficient input sanitization and output escaping. This allows 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.

Recommendations For versions up to, and including, 1.4.1, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the add custom body class value to minimize the risk of exploitation.
