This high-severity CVE scores 7.0 under NVD CVSS v3. EPSS exploit probability: 1.0%, top 40% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Istio is an open platform to connect, manage, and secure microservices. In affected versions ill-formed headers sent to Envoy in certain configurations can lead to unexpected memory access resulting in undefined behavior or crashing. Users are most likely at risk if they have an Istio ingress Gateway exposed to external traffic. This vulnerability has been resolved in versions 1.12.8, 1.13.5, and 1.14.1. Users are advised to upgrade. There are no known workarounds for this issue.
