CVE-2026-47206

Dragonfly is an in-memory data store built for modern application workloads. Prior to 1.39.9, Dragonfly has a RESP Protocol Injection via Lua redis.error_reply() in EvalSerializer. An authenticated user can inject arbitrary RESP messages into the connection's response stream, potentially causing response desynchronization in connection-pool clients. This vulnerability is fixed in 1.39.9.
