Name of the Vulnerable Software and Affected Versions Custom post types, Custom Fields & more plugin for WordPress versions up to, and including, 5.0.4

Description The issue arises from insufficient input sanitization and output escaping on user-supplied post meta values, allowing authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages. This can lead to the execution of injected scripts whenever a user accesses an affected page.

Recommendations For versions up to, and including, 5.0.4, update to a version later than 5.0.4 to resolve the issue. As a temporary workaround, consider restricting access to the plugin's shortcode and custom post meta features to minimize the risk of exploitation.
