description

REDCap 13.3.0 and later are affected by flaws in public-survey request routing and import handling. An unauthenticated attacker who knows a valid public survey hash could execute code on the REDCap server.

mitigation

Restrict network access to REDCap and disable public survey exposure where operationally feasible. Limit distribution of public survey links and apply a vendor update when a fixed release is provided.
