This vulnerability poses a significant risk as it can lead to unauthorized access and control over critical infrastructure components. Organizations using these products, particularly those with complex node configurations, should prioritize upgrading to the patched versions to mitigate this high-severity risk.

Original NVD Description
Consul and Consul Enterprise are vulnerable to an authorization bypass in the catalog node-write path that may allow an authenticated attacker to delete another node's catalog registration and take over its node identity. An attacker with a token granting node-write permission on any single node name may exploit this issue if they can obtain the node ID of a node they do not control. This vulnerability (CVE-2026-87090) is fixed in Consul 2.0.4 and Consul Enterprise 1.21.18, 1.22.12 and 2.0.4.
