CVE-2026-97685

LimeSurvey Community Edition 7.3.0 - Cross-survey object authorization bypass in REST survey patch operations

An authenticated LimeSurvey Community Edition 7.3.0 user allowed to create surveys can use their own survey as an authorized context while supplying question or answer identifiers belonging to another user's survey. The REST survey-patching endpoint checks the attacker's permission against the survey ID in the request URL, but the vulnerable persistence operations resolve the target object independently by its global qid or aid and never verify that it belongs to that authorized survey.
