9.2 CRITICALEPSS 0.17%
  1. Published15 Jul 2026

Description

Cilium is a networking, observability, and security solution. Prior to 1.17.14, 1.18.8, and 1.19.2, when Cilium L7 functionality is enabled, the embedded or standalone Envoy instance creates a world-accessible admin.sock on cluster nodes, allowing a local attacker to access Envoy admin endpoints, expose TLS secrets, disrupt cluster traffic, or terminate Envoy. This issue is fixed in versions 1.17.14, 1.18.8, and 1.19.2.
