AI-suggested
Upgrade DragonflyDB to version 1.39.0 or later, where this vulnerability is fixed. Until upgrading, consider restricting access to the RESTORE command or implementing authentication if possible to reduce exposure. Patch status is confirmed fixed in version 1.39.0.
Description
Dragonfly is an in-memory data store built for modern application workloads. Prior to 1.39.0, a crafted RESTORE payload triggers an out-of-bounds read in DragonflyDB's listpack collection loaders, crashing the entire server process (SIGSEGV). Because DragonflyDB requires no authentication by default and RESTORE is a normal keyspace command, an unauthenticated remote attacker can crash the server with a single ~24-byte command — a remote, repeatable denial of service. This vulnerability is fixed in 1.39.0.
