{"id":"GHSA-2gvw-w6fj-7m3c","summary":"Argo CD's API server does not enforce project sourceNamespaces","details":"### Impact\n\nI can convince the UI to let me do things with an invalid Application.\n1. Admin gives me `p, michael, applications, *, demo/*, allow`, where `demo` can just deploy to the `demo` namespace\n2. Admin gives me AppProject `dev` which reconciles from ns `dev-apps`\n3. Admin gives me `p, michael, applications, sync, dev/*, allow`, i.e. no updating via the UI allowed, gitops-only\n4. I create an Application called `pwn` in `dev-apps` with project dev and sync the app with sources from git\n5. I change the Application’s project to demo via kubectl or gitops (whichever mechanism my admins have given me, because it should be safe)\n6. I use the UI to edit the resource which should only be mutable via gitops\n\n### Patches\nA patch for this vulnerability has been released in the following Argo CD versions:\n\nv2.10.7 \nv2.9.12 \nv2.8.16\n\n### For more information\nIf you have any questions or comments about this advisory:\n\nOpen an issue in [the Argo CD issue tracker](https://github.com/argoproj/argo-cd/issues) or [discussions](https://github.com/argoproj/argo-cd/discussions)\nJoin us on [Slack](https://argoproj.github.io/community/join-slack) in channel #argo-cd\n\n### Credits\nThis vulnerability was found & reported by @crenshaw-dev (Michael Crenshaw)\n\nThe Argo team would like to thank these contributors for their responsible disclosure and constructive communications during the resolve of this issue\n","aliases":["BIT-argo-cd-2024-31990","CVE-2024-31990","GO-2024-2728"],"modified":"2026-08-07T08:12:26.158528849Z","published":"2024-04-15T20:20:50Z","database_specific":{"nvd_published_at":"2024-04-15T20:15:11Z","cwe_ids":["CWE-863"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2024-04-15T20:20:50Z"},"references":[{"type":"WEB","url":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-2gvw-w6fj-7m3c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-31990"},{"type":"WEB","url":"https://github.com/argoproj/argo-cd/commit/c514105af739eebedb9dbe89d8a6dd8dfc30bb2c"},{"type":"WEB","url":"https://github.com/argoproj/argo-cd/commit/c5a252c4cc260e240e2074794aedb861d07e9ca5"},{"type":"WEB","url":"https://github.com/argoproj/argo-cd/commit/e0ff56d89fbd7d066e9c862b30337f6520f13f17"},{"type":"PACKAGE","url":"https://github.com/argoproj/argo-cd"}],"affected":[{"package":{"name":"github.com/argoproj/argo-cd/v2","ecosystem":"Go","purl":"pkg:golang/github.com/argoproj/argo-cd/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.4.0"},{"fixed":"2.8.16"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/04/GHSA-2gvw-w6fj-7m3c/GHSA-2gvw-w6fj-7m3c.json"}},{"package":{"name":"github.com/argoproj/argo-cd/v2","ecosystem":"Go","purl":"pkg:golang/github.com/argoproj/argo-cd/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.9.0"},{"fixed":"2.9.12"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/04/GHSA-2gvw-w6fj-7m3c/GHSA-2gvw-w6fj-7m3c.json"}},{"package":{"name":"github.com/argoproj/argo-cd/v2","ecosystem":"Go","purl":"pkg:golang/github.com/argoproj/argo-cd/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.10.0"},{"fixed":"2.10.7"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/04/GHSA-2gvw-w6fj-7m3c/GHSA-2gvw-w6fj-7m3c.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:N/I:N/A:H"}]}
