CVE-2026-87107

Estado: Pendiente de análisisMedia (5.4)—

Consul and Consul Enterprise are vulnerable to an authorization bypass in the catalog deregistration path that may allow a local ACL token to delete peer-imported catalog objects. A caller with {{service:write}} or {{node:write}} permission may exploit this issue to remove services, checks, or nodes imported from a peered cluster without holding authority over the peer origin. This vulnerability (CVE-2026-87107) is fixed in Consul 2.0.4 and Consul Enterprise 1.21.18, 1.22.12 and 2.0.4.
