AI-analyzed exploit summary This repository contains a functional exploit for CVE-2026-23631, targeting a Redis Lua scripting vulnerability. The exploit uses a multi-stage approach involving memory corruption, fake object manipulation, and RDB payload delivery to achieve remote code execution.
Description
Redis is an in-memory data structure store. In all versions of redis-server with Lua scripting, an authenticated attacker can exploit the master-replica synchronization mechanism to trigger a use-after-free on replicas where replica-read-only is disabled or can be disabled, which may lead to remote code execution. A workaround is to prevent users from executing Lua scripts or avoid using replicas where replica-read-only is disabled. This is patched in version 8.6.3.
