Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. In versions 2.13.0 through 2.13.8, 2.14.0 through 2.14.15, 3.0.0 through 3.0.12 and 3.1.0-rc1 through 3.1.1, API tokens with project-level permissions are able to retrieve sensitive repository credentials (usernames, passwords) through the project details API endpoint, even when the token only has standard application management permissions and no explicit access to secrets. This issue also affects any token with “project get” permissions, including global roles such as p, role/user, projects, get, *, allow. Fixed in versions 2.13.9, 2.14.16, 3.0.14 and 3.1.2.
The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. A partial list of potentially affected assets is listed in this post.
