Description

Argo Events is an event-driven workflow automation framework for Kubernetes. Prior to version 1.7.1, several `HandleRoute` endpoints make use of the deprecated `ioutil.ReadAll()`. `ioutil.ReadAll()` reads all the data into memory. As such, an attacker who sends a large request to the Argo Events server will be able to crash it and cause denial of service. A patch for this vulnerability has been released in Argo Events version 1.7.1.

Affected products

• argoproj argo-events: before 1.7.1 — fixed in 1.7.1

How to fix

Upgrade to a fixed version: argoproj argo-events 1.7.1. Check the vendor advisory for mitigations.
