CVE-2026-75106

Name of the Vulnerable Software and Affected Versions OpnForm (affected versions not specified)

Description The software derives editable-submission secrets from sequential row identifiers using Hashids with an empty default salt. This allows unauthenticated attackers to compute hashes for any submission. Consequently, attackers can read full submission data via the 'submission-fetch' endpoint or overwrite submissions by providing predicted hashes to the 'answer' endpoint.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
