Name of the Vulnerable Software and Affected Versions Advanced Custom Fields (ACF) plugin for WordPress versions up to, and including, 6.2.4

Description The issue is related to Stored Cross-Site Scripting via a custom text field 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, 6.2.4, update to a version higher than 6.2.4 to resolve the issue. As a temporary workaround, consider restricting access to custom text fields for users with contributor-level access and above until a patch is available.
