CVE-2025-54472Network attack vector

Service crash via unbounded Redis parser allocation

Published Aug 14, 2025 · Updated Nov 4, 2025

Uncontrolled resource consumption in Apache bRPC before 1.14.1 allows remote attackers to crash Redis-enabled services via crafted traffic. The Redis protocol parser allocates arrays and strings from network-supplied integer lengths; in 1.14.0, integer overflow bypasses its allocation limit. Exposure requires a bRPC Redis server to accept untrusted clients or a bRPC Redis client to consume replies from an untrusted service.
