Descripción
OpnForm derives editable-submission secrets from sequential row identifiers using Hashids with an empty default salt, allowing unauthenticated attackers to compute hashes for any submission. Attackers can read other respondents- full submission data through the submission-fetch endpoint or overwrite submissions by supplying predicted hashes to the answer endpoint.
