AI-suggested

A patch is available and should be applied by upgrading Redis to version 8.2.2 or later. Alternatively, if patching is not immediately possible, restrict Lua script execution by using ACLs to block the EVAL and FUNCTION command families, preventing users from running Lua scripts. This workaround reduces exposure until the official fix is deployed.

Description

Redis versions 8.2.1 and below with Lua scripting enabled contain a vulnerability that allows an authenticated user to execute specially crafted Lua scripts to read out-of-bound memory or crash the server, causing denial of service. This issue affects all Redis versions with Lua scripting and is fixed in version 8.2.2. A workaround without patching is to restrict Lua script execution using ACL to block EVAL and FUNCTION commands.
