CVE-2023-47004Network attack vector

Authenticated code execution via undisclosed buffer overflow

Published Nov 6, 2023 · Updated Apr 29, 2025

Buffer overflow in RedisGraph 2.0.0 through 2.12.8 allows remote authenticated users to execute arbitrary code over the Redis service. The public record identifies an out-of-bounds write in post-authentication code logic but does not disclose the affected function, buffer, or triggering input. Valid Redis credentials and network access are required; successful exploitation runs attacker-controlled code in the Redis server's security context.
