What is CVE-2023-36824?

An identified vulnerability in Redis versions prior to 7.0.12 involves a heap overflow that can occur when key names are extracted from commands with varying arguments. This flaw may lead to heap corruption and allows for reading arbitrary memory, potentially enabling authenticated users to execute specially crafted commands such as COMMAND GETKEYS or COMMAND GETKEYSANDFLAGS. This represents a critical risk as attackers could leverage these commands in environments where ACL rules have been configured to align with key names.
