Name of the Vulnerable Software and Affected Versions: The Guten Post Layout – An Advanced Post Grid Collection for WordPress versions up to, and including, 1.2.4

Description: The issue is related to Stored Cross-Site Scripting via the align attribute within the 'wp:guten-post-layout/post-grid' Gutenberg block 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, 1.2.4, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the 'wp:guten-post-layout/post-grid' Gutenberg block to minimize the risk of exploitation. Additionally, limiting Contributor-level access and above can help reduce the potential impact of this issue until a patch is applied.
