| CRE-2025-0039 Medium Impact: 5/10 Mitigation: 3/10 | OpenTelemetry Collector exporter experiences retryable errors due to backend unavailability | The OpenTelemetry Collector may intermittently fail to export telemetry data when the backend API is unavailable or overloaded. These failures manifest as timeouts (`context deadline exceeded`) or transient HTTP 502 responses. While retry logic is typically enabled, repeated failures can introduce delay or backpressure. | Observability Problems | opentelemetry-collector | Otel CollectorExporterTimeoutRetryNetworkTelemetryKnown IssuePublic |
| CRE-2025-0111 Medium Impact: 8/10 Mitigation: 7/10 | Ztunnel IPv6 Bind Failure | Detects when Ztunnel's DNS proxy or control-plane component attempts to bind to the IPv6 loopback address `[::1]:15053` on a node where IPv6 is disabled, resulting in an `Address family not supported` error. | Istio Ambient Troubleshooting | ambient | IstioAmbientZtunnelNetwork |
| CRE-2025-0126 High Impact: 10/10 Mitigation: 7/10 | MongoDB Replica Set Primary Election Failure | Detects high-severity MongoDB replica set primary election failures that result in no primary node being available, causing complete service unavailability. This rule targets catastrophic conditions that break replica set consensus: - Primary node failures followed by election timeouts where no secondary can become primary - Network partitions isolating replica set members and preventing quorum formation - Heartbeat failures and connectivity issues leading to election failures - Replica set state transitions indicating election problems | Database Problems | mongodb | High AvailabilityQuorumLeader ElectionNetworkTimeoutCrashData Loss |
| CRE-2025-0132 Medium Impact: 8/10 Mitigation: 5/10 | Supabase Self-Hosted: Database Connection Timeout and Service Failure | Detects when Supabase services lose connection to the PostgreSQL database due to timeouts, network issues, or database unavailability. This affects Auth, REST API, Storage, and all database-dependent operations. Occurs during database restarts, network partitions, or when database becomes unresponsive. | Database Problems | supabase | SupabasePostgreSQLConnectionTimeoutNetworkSelf-HostedConnectivityPublic |
| 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 | RedisConnectionTimeoutConnectivityNetwork |
