Name of the Vulnerable Software and Affected Versions Custom Field Suite plugin for WordPress versions up to, and including, 2.6.4

Description The issue is related to Stored Cross-Site Scripting via a meta import due to insufficient input sanitization and output escaping on the meta values. This allows authenticated attackers with administrator-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The issue only affects multi-site installations and installations where unfiltered html has been disabled.

Recommendations For versions up to, and including, 2.6.4, update to a version higher than 2.6.4 to resolve the issue. As a temporary workaround, consider restricting access to the meta import feature to minimize the risk of exploitation. Additionally, ensure that unfiltered html is enabled, if possible, to reduce the vulnerability's impact.
