CVE-2024-6305

Name of the Vulnerable Software and Affected Versions: WordPress Core versions up to 6.5.5

Description: The issue is related to Stored Cross-Site Scripting via the Template Part Block due to insufficient input sanitization and output escaping on the tagName attributes. 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 6.5.5, update to a version that contains a fix for this issue to prevent exploitation. As a temporary workaround, consider restricting access to the Template Part Block feature for users with contributor-level access and above until a patch is available.
