Advisory
Source description from Wordfence Intelligence, credited to Ngô Thiên An (ancorn_).
The Otter Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the id parameter in the google-map block in all versions up to, and including, 2.6.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with contributor access and higher to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
