    Summary: Excessive CPU usage when URI template matcher is configured using regex in Envoy

    Details: Envoy is a high-performance edge/middle/service proxy.

This issue has been addressed in released 1.29.1, 1.28.1, 1.27.3, and 1.26.7. Users are advised to upgrade. There are no known workarounds for this vulnerability.
