A flaw was found in Consul. A remote attacker could exploit an uncontrolled resource consumption vulnerability in the Connect authorization endpoint. This flaw allows a caller to continuously grow the agent's intention-match cache, bypassing configured cache limits. The primary consequence is a Denial of Service (DoS) due to unbounded resource consumption.

Description OSIDB Bzimport 2026-08-07 19:41:50 UTC
Consul Community Edition and Consul Enterprise 1.17.0 through 2.0.2 are vulnerable to an uncontrolled resource consumption issue in the Connect authorization endpoint that may allow a caller to grow the agent's intention-match cache without bound, defeating the operator's cache-disable configuration. This vulnerability, CVE-2026-190124, is fixed in Consul 2.0.3 and Consul Enterprise 1.21.17, 1.22.11, and 2.0.3.
