CVE-2024-21652: Argoproj Argo Cd

Critical severity, CVSS 9.8. EPSS: 0.8% chance of exploitation in the next 30 days.

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Prior to versions 2.8.13, 2.9.9, and 2.10.4, an attacker can exploit a chain of vulnerabilities, including a Denial of Service (DoS) flaw and in-memory data storage weakness, to effectively bypass the application's brute force login protection. This is a critical security vulnerability that allows attackers to bypass the brute force login protection mechanism. Not only can they crash the service affecting all users, but they can also make unlimited login attempts, increasing the risk of account compromise. Versions 2.8.13, 2.9.9, and 2.10.4 contain a patch for this issue.

Affected products

• Argoproj Argo Cd: before 2.8.13 (fixed in 2.8.13); from 2.9.0, before 2.9.9 (fixed in 2.9.9); from 2.10.0, before 2.10.4 (fixed in 2.10.4)
