The kustomize-controller enables the use of Kustomize’s functionality when applying Kubernetes declarative state onto a cluster. A malicious user can use a specially crafted `kustomization.yaml` to cause Denial of Service at controller level. In multi-tenancy deployments this can lead to multiple tenants not being able to apply their Kustomizations until the malicious `kustomization.yaml` is removed and the controller restarted. ### Impact Within the affected versions, users with write access to a Flux source are able to craft a malicious `kustomization.yaml` file which causes the controller to enter an endless loop. ### Patches This vulnerability was fixed in kustomize-controller v0.24.0 and included in flux2 v0.29.0 released on 2022-04-20. The changes introduce better handling of Kustomization files blocking references that could lead to endless loops. ### Credits The Flux engineering team found and patched this vulnerability. ### For more information If you have any questio...

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. A critical vulnerability has been discovered in Argo CD starting with version 1.4.0 and prior to versions 2.1.15, 2.2.9, and 2.3.4 which would allow unauthenticated users to impersonate as any Argo CD user or role, including the `admin` user, by sending a specifically crafted JSON Web Token (JWT) along with the request. In order for this vulnerability to be exploited, anonymous access to the Argo CD instance must have been enabled. In a default Argo CD installation, anonymous access is disabled. The vulnerability can be exploited to impersonate as any user or role, including the built-in `admin` account regardless of whether it is enabled or disabled. Also, the attacker does not need an account on the Argo CD instance in order to exploit this. If anonymous access to the instance is enabled, an attacker can escalate their privileges, effectively allowing them to gain the same privileges on the cluster as the Argo ...

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. A vulnerability was found in Argo CD prior to versions 2.3.4, 2.2.9, and 2.1.15 that allows an attacker to spoof error messages on the login screen when single sign on (SSO) is enabled. In order to exploit this vulnerability, an attacker would have to trick the victim to visit a specially crafted URL which contains the message to be displayed. As far as the research of the Argo CD team concluded, it is not possible to specify any active content (e.g. Javascript) or other HTML fragments (e.g. clickable links) in the spoofed message. A patch for this vulnerability has been released in Argo CD versions 2.3.4, 2.2.9, and 2.1.15. There are currently no known workarounds.
