Summary

The Otter Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.2.6 via the 'otter_form_widget_filter' parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract the email addresses of the five most recent form submitters, their submission dates, and the site's total form submission count. The widget is registered whenever the themeisle_blocks_form_emails option is non-empty — the normal state after any Form block has been saved — meaning the exposure is active on any standard site using the plugin's form feature.
