Published: 2022-06-09 · updated 2026-06-17
Weakness: CWE-617

Description

Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 the OAuth filter would try to invoke the remaining filters in the chain after emitting a local response, which triggers an ASSERT() in newer versions and corrupts memory on earlier versions. continueDecoding() shouldn’t ever be called from filters after a local reply has been sent. Users are advised to upgrade. There are no known workarounds for this issue.

Affected products

envoyproxy envoy: before 1.22.1 — fixed in 1.22.1

How to fix

Upgrade to a fixed version: envoyproxy envoy 1.22.1. Check the vendor advisory for mitigations.
