BIT-REDIS-2021-32626 Lua scripts can overflow the heap-based Lua stack in Redis
Redis is an open source, in-memory database that persists on disk. In affected versions specially crafted Lua scripts executing in Redis can cause the heap-based Lua stack to be overflowed, due to incomplete checks for this condition. This can result with heap corruption and potentially remote co...
BIT-REDIS-2021-32672 Vulnerability in Lua Debugger in Redis
Redis is an open source, in-memory database that persists on disk. When using the Redis Lua Debugger, users can send malformed requests that cause the debugger’s protocol parser to read data beyond the actual buffer. This issue affects all versions of Redis with Lua debugging support 3.2 or newer...

BIT-REDIS-2022-24735 Lua scripts can be manipulated to overcome ACL rules in Redis
Redis is an in-memory database that persists on disk. By exploiting weaknesses in the Lua script execution environment, an attacker with access to Redis prior to version 7.0.0 or 6.2.7 can inject Lua code that will execute with the potentially higher privileges of another Redis user. The Lua scri...
