What is CVE-2024-40634?

Argo CD is a widely used GitOps continuous delivery tool for Kubernetes that has a vulnerability allowing unauthenticated attackers to exploit the /api/webhook endpoint. By sending a specifically crafted large JSON payload, the vulnerability causes excessive memory allocation, which can trigger an Out Of Memory (OOM) kill, resulting in a substantial risk to the availability of the Argo CD service. This issue highlights potential weaknesses in the application’s handling of inputs and requires immediate attention to mitigate risks. The vulnerability has been addressed in recent updates, specifically in versions 2.11.6, 2.10.15, and 2.9.20.
