redis,valkey -- Running Lua function as a different user

redis reports:

An authenticated user may use a specially crafted Lua script to manipulate different LUA objects and potentially run their own code in the context of another user The problem exists in all versions of Redis with Lua scripting. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from executing Lua scripts. This can be done using ACL to block a script by restricting both the EVAL and FUNCTION command families.
