CVE-2024-3559

Name of the Vulnerable Software and Affected Versions Custom Field Suite plugin for WordPress versions up to, and including, 2.6.7

Description The issue is related to Stored Cross-Site Scripting via the cfs[post content] parameter 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, which will execute when a user accesses an injected page.

Recommendations For versions up to, and including, 2.6.7, update to a version that addresses the insufficient input sanitization and output escaping issue to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the cfs[post content] parameter to minimize the risk of exploitation.
