EUVD-2026-107185

Resource exhaustion in Apache bRPC version 1.18.0 on all platforms: multiple parsers that accept wire-controlled input bound no limit on the sizes declared by the client or on decompressed output, which attackers can use to drive disproportionate memory use and crash the process. Root Cause: 1 Th...
