BIT-VALKEY-2023-45145 Redis Unix-domain socket may have be exposed with the wrong permissions for a short time window.
Redis is an in-memory database that persists on disk. On startup, Redis begins listening on a Unix socket before adjusting its permissions to the user-provided configuration. If a permissive umask2 is used, this creates a race condition that enables, during a short period of time, another process...
