Detailed vulnerability description
The vulnerability allows a remote user to cause a denial of service.
The vulnerability exists due to a race condition in repository credentials handlers in util/db/repository_secrets.go when processing concurrent repository credential operations on the same repository URL. A remote user can send concurrent create, update, or delete operations for repository credentials to cause a denial of service.
The issue can panic the Argo CD server through concurrent map read and write access, and repeated triggering can keep the server unavailable.
