CRE-2025-0030 Medium Impact: 6/10 Mitigation: 2/10	SQLAlchemy create_engine fails when password contains special characters like @	SQLAlchemy applications using `create_engine()` may fail to connect to a database if the username or password contains special characters (e.g., `@`, `:`, `/`, `#`). These characters must be URL-encoded when included in the database connection string. Failure to encode them leads to parsing errors or incorrect credential usage.

CRE-2025-0140 Medium Impact: 6/10 Mitigation: 5/10	Supabase Self-Hosted: Realtime Service Crash Due to Invalid Configuration	Detects when Supabase Realtime service fails to start or crashes due to invalid configuration parameters. This affects WebSocket connections, real-time subscriptions, and live data streaming capabilities. Common issues include invalid replication modes, missing database permissions, or incorrect environment variables.

CRE-2025-0173 Critical Impact: 10/10 Mitigation: 7/10	Redis Connection Timeout and Connectivity Issues	Detects Redis connection timeout errors and connectivity failures that prevent clients from establishing or maintaining connections to the Redis server. These issues commonly occur during high load, network problems, or server resource exhaustion.	In-Memory Database Problems	redis	Redis Connection Timeout Connectivity Network
CRE-2025-0181 Critical Impact: 10/10 Mitigation: 7/10	Redis Maximum Client Connections Limit Exceeded	Detects when Redis reaches its maximum client connection limit, preventing new clients from connecting. This critical issue causes connection failures and service unavailability for new requests.	In-Memory Database Problems	redis	Redis Connection Max Clients Connection Pool Limit
