Deserialization of untrusted data in the Gremlin graph data import component in Amazon Neptune engine might allow an authenticated remote actor with standard database permissions to execute arbitrary code and access internal service credentials.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.36%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
