Vulnerable vs. safe
Flagged by this check
Oj.load(request.body.read, mode: :object)Passes - the safe pattern
Oj.load(request.body.read, mode: :strict)Why it matters & how to fix it
Oj is used in :object mode, which deserializes arbitrary Ruby object types and enables RCE on untrusted input (CWE-502). Use a safe Oj mode (:strict or :compat) for external data so only plain JSON types are produced.
