CVE-2025-0754Network attack vector

Log spoofing via unneutralized forwarded header

Published Jan 28, 2025 · Updated Nov 20, 2025

Log injection in Envoy within Red Hat OpenShift Service Mesh 2.5.6 and 2.6.3 allows remote authenticated users to spoof request records. Envoy writes the unneutralized x-forwarded-for request header into service-mesh logs, letting crafted values forge entries or become script content. A low-privileged network identity and access to a logged HTTP path are required; impact is limited to log integrity and reflected XSS in susceptible log viewers.
