Description
Hatchet through 0.110.5 contains an allocation of resources without limits vulnerability that allows unauthenticated attackers to exhaust memory via the SNS ingestion endpoint. Attackers can send arbitrarily large or concurrent request bodies to POST /api/v1/sns/{tenant}/{event} with any UUID, which the SnsUpdate handler buffers before signature verification, degrading availability.
