CVE-2024-21661

Summary

CVE-2024-21661 is a Denial of Service (DoS) vulnerability affecting Argo CD, a popular continuous delivery tool for Kubernetes, prior to versions 2.8.13, 2.9.9, and 2.10.4. An attacker can exploit unsafe array manipulation in a multi-threaded environment, leading to application crashes and rendering the service inoperable for all users. The vulnerability arises when the application modifies an array while it is being iterated over, causing a classic programming error with catastrophic consequences in a multi-threaded environment. With no authentication required to exploit this issue, the DoS attack surface is significantly expanded. The affected versions have been patched in 2.8.13, 2.9.9, and 2.10.4.
