Name of the Vulnerable Software and Affected Versions The Otter Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE plugin for WordPress versions up to, and including, 2.6.9

Description The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping on user-supplied attributes such as titleTag. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages, which will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 2.6.9, 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 Post Grid widget for users with contributor-level access and above until a patch is available.
