GHSA-2gvw-w6fj-7m3c

Argo CD's API server does not enforce project sourceNamespaces

Description

### Impact I can convince the UI to let me do things with an invalid Application. 1. Admin gives me `p, michael, applications, *, demo/*, allow`, where `demo` can just deploy to the `demo` namespace 2. Admin gives me AppProject `dev` which reconciles from ns `dev-apps` 3. Admin gives me `p, michael, applications, sync, dev/*, allow`, i.e. no updating via the UI allowed, gitops-only 4. I create an Application called `pwn` in `dev-apps` with project dev and sync the app with sources from git 5. I change the Application’s project to demo via kubectl or gitops (whichever mechanism my admins have given me, because it should be safe) 6. I use the UI to edit the resource which should only be mutable via gitops ### Patches A patch for this vulnerability has been released in the following Argo CD versions: v2.10.7 v2.9.12 v2.8.16 ### For more information If you have any questions or comments about this advisory: Open an issue in [the Argo CD issue tracker](https://github.com/argoproj/argo-cd/issues) or [discussions](https://github.com/argoproj/argo-cd/discussions) Join us on [Slack](https://argoproj.github.io/community/join-slack) in channel #argo-cd ### Credits This vulnerability was found & reported by @crenshaw-dev (Michael Crenshaw) The Argo team would like to thank these contributors for their responsible disclosure and constructive communications during the resolve of this issue
