Description OSIDB Bzimport 2026-08-07 19:41:39 UTC 
Consul Community Edition and Consul Enterprise 1.20.1 through 2.0.2 are vulnerable to an L7 intention authorization bypass when a service proxy is configured with a custom public listener. An authenticated mesh workload may reach HTTP paths that are blocked by a path-based deny intention. This vulnerability, CVE-2026-15970, is fixed in Consul 2.0.3 and Consul Enterprise 1.21.17, 1.22.11, and 2.0.3.
