Unauthenticated denial of service via unbounded external gRPC connection acceptance
Consul Community Edition and Consul Enterprise 1.13.0 through 2.0.2 are vulnerable to an unauthenticated denial of service through unbounded connection acceptance on the external gRPC listeners. A remote attacker may exhaust agent file descriptors, goroutines, and memory by opening many incomplete connections, potentially preventing legitimate clients from connecting. This vulnerability, CVE-2026-15972, is fixed in Consul 2.0.3 and Consul Enterprise 1.21.17, 1.22.11, and 2.0.3.
