Description
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.

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.
