Name of the Vulnerable Software and Affected Versions: Attributes for Blocks plugin for WordPress versions up to, and including, 1.0.6

Description: The issue is related to Stored Cross-Site Scripting via the attributesForBlocks 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 that will execute whenever a user accesses an injected page.

Recommendations: For versions up to, and including, 1.0.6, update to a version later than 1.0.6 to resolve the issue. As a temporary workaround, consider restricting access to the attributesForBlocks parameter to minimize the risk of exploitation.
