AI-analyzed exploit summary This repository contains a functional exploit PoC for CVE-2026-25243, which targets an invalid memory access vulnerability in the Redis RESTORE command. The exploit leverages a crafted payload to trigger a heap-based buffer overflow, potentially leading to remote code execution.
Description
Redis is an in-memory data structure store. In versions of redis-server up to 8.6.3, the RESTORE command does not properly validate serialized values. An authenticated attacker with permission to execute RESTORE can supply a crafted serialized payload that triggers invalid memory access and may lead to remote code execution. A workaround is to restrict access to the RESTORE command with ACL rules. This is patched in version 8.6.3.
