CVE-2022-31144Network attack vector

Code execution via undersized XAUTOCLAIM reply array

Published Jul 19, 2022 · Updated Apr 23, 2025

Heap-based buffer overflow in Redis 7.0.0 through 7.0.3 allows remote authenticated users to execute code via a crafted XAUTOCLAIM command. The xautoclaimCommand function allocates a temporary deleted-entry reply array from COUNT but fails to decrement that limit when deleted pending entries are appended, allowing writes past the allocation. A low-privileged user able to issue XAUTOCLAIM must first place a stream consumer group in the required deleted-pending-entry state; successful corruption can crash the server or execute code in its process.
