Note: added the actual report as a comment.
Decidim, a platform for digital citizen participation, uses a third-party library named Ransack for filtering certain database collections (e.g., public meetings). By default, this library allows filtering on all data attributes and associations. This allows an unauthenticated remote attacker to exfiltrate non-public data from the underlying database of a Decidim instance (e.g., exfiltrating data from the user table).
This issue may lead to Sensitive Data Disclosure.
The problem was patched in v0.27.3.
Disable or unpublish all meetings components from your application.
