CVE-2021-39206 is a high-severity vulnerability affecting Pomerium, an identity-aware access proxy, and its underlying Envoy framework. It stems from two authorization flaws (CVE-2021-32777, CVE-2021-32779) in Envoy, which can lead to incorrect routing or authorization decisions in Pomerium when processing specially crafted requests, specifically with path prefix-based policies. The vulnerability has a CVSS score of 8.6 (High), indicating it can be exploited remotely with low complexity, resulting in high integrity impact without user interaction. While patches exist in Pomerium v0.14.8 and v0.15.1, there is no evidence of active exploitation, public exploit code, or significant community discussion.
