Envoy is a cloud-native high-performance edge/middle/service proxy. A vulnerability has been identified in Envoy that allows malicious attackers to inject unexpected content into access logs. This is achieved by exploiting the lack of validation for the REQUESTED_SERVER_NAME
field for access loggers. This issue has been addressed in versions 1.31.2, 1.30.6, 1.29.9, and 1.28.7. Users are advised to upgrade. There are no known workarounds for this vulnerability.
The product does not neutralize or incorrectly neutralizes output that is written to logs.
