Technical details
The vulnerability is a cross-object authorization bypass in the REST survey-patching endpoint. The endpoint validates that the attacker has permission for the survey ID in the request URL, but the underlying persistence operations resolve question (qid) and answer (aid) identifiers globally without verifying these objects belong to the authorized survey. An authenticated attacker with survey creation privileges can supply identifiers from another user's survey to modify their content.
