CVE-2022-31045 is a critical vulnerability affecting Istio, an open platform for managing microservices. Ill-formed headers sent to Envoy in specific configurations can cause unexpected memory access, leading to undefined behavior or crashes, particularly impacting Istio ingress Gateways exposed to external traffic. With a CVSS score of 9.8 (Critical), this vulnerability is remotely exploitable with low attack complexity, potentially leading to high impact on confidentiality, integrity, and availability. While no active exploitation, public exploit code, or significant community discussion has been observed, users are strongly advised to upgrade to versions 1.12.8, 1.13.5, or 1.14.1, as no workarounds exist.
