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, 2.6.5

Description The issue is related to Stored Cross-Site Scripting via the plugin's widgets due to insufficient input sanitization and output escaping on user-supplied attributes such as id. 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, 2.6.5, update to a version later than 2.6.5 to resolve the issue. As a temporary workaround, consider restricting access to the plugin's widgets for users with contributor-level access and above until a patch is available. Avoid using the id attribute in the affected widgets to minimize the risk of exploitation.
