From version 4.0.0 to before version 4.0.5, the Sync Service's ConfigMap-backed provider (server/sync/sync_cm.go) performs zero authorization checks on all CRUD operations (create, read, update, delete). Any authenticated user — including those using fake Bearer tokens — can create, read, update, and delete Kubernetes ConfigMaps containing synchronization limits. This issue has been patched in version 4.0.5.","published":"2026-05-09T03:42:43.305Z","modified":"2026-07-31T18:30:03.323036528Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-workflows/v4","fixedVersion":"4.0.5"}],"fix":{"url":"https://github.com/argoproj/argo-workflows/commit/09fff05e0830c14a5e36cc40597ad84881db1ab6","label":"argoproj/argo-workflows@09fff05"},"references":[{"type":"WEB","url":"https://github.com/argoproj/argo-workflows/releases/tag/v4.0.5"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-42297.json"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-42297"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42297.json"},{"type":"ADVISORY","url":"https://github.com/argoproj/argo-workflows/security/advisories/GHSA-xchc-cqwg-g76q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42297"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2468448"},{"type":"FIX","url":"https://github.com/argoproj/argo-workflows/commit/09fff05e0830c14a5e36cc40597ad84881db1ab6"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-31T18:30:03.323036528Z"}}
