Vulnerability details
The vulnerability allows an unauthenticated remote attacker to consume server resources beyond Gotenberg's configured request body limit.
The vulnerability exists due to enforcement of api-body-limit only after complete multipart parsing when a positive limit is configured. An unauthenticated remote attacker can submit an oversized body to a reachable multipart conversion route within api-timeout, causing the entire request to be read and parsed before rejection.
