Technical details
A sensitive information disclosure vulnerability exists in Everest Forms (specifically when the Pro add-on is active) due to improper cleanup of temporary artifacts. When a form is configured with multiple email notifications and a CSV attachment is enabled on a notification that is not the last one processed, the plugin fails to delete the generated CSV file from the '/uploads/Everes-Froms-Entries-CSV-file/' directory. Because form entry IDs are sequential and disclosed in the submission response, unauthenticated attackers can enumerate and download these CSV files. The issue is fixed in version 3.5.0.
