Technical details
The batch-requests plugin in Apache APISIX lacks resource limits or request throttling, allowing attackers to submit unbounded batch requests. An unauthenticated, network-based attacker can craft oversized requests to a publicly exposed batch endpoint with minimal preconditions, triggering out-of-memory exhaustion in gateway worker processes. The vulnerability is fixed in version 3.19.0.
