{"id":"CVE-2026-42297","summary":"Argo Workflows Is Missing Authorization in Sync ConfigMap Provider","details":"Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. 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.","aliases":["BIT-argo-workflows-2026-42297","GHSA-xchc-cqwg-g76q","GO-2026-5751"],"modified":"2026-07-16T03:31:00.538622960Z","published":"2026-05-09T03:42:43.305Z","related":["CGA-v754-m8c5-6gg7"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42297.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/argoproj/argo-workflows","events":[{"introduced":"a8bff4a72130bc1a13d95c6f73ff3fafec880287"},{"fixed":"0ab1452144d8f4d57c50b37ce50dad218868e950"},{"fixed":"09fff05e0830c14a5e36cc40597ad84881db1ab6"}],"database_specific":{"cpe":"cpe:2.3:a:argoproj:argo_workflows:*:*:*:*:*:go:*:*","extracted_events":[{"introduced":"4.0.0"},{"fixed":"4.0.5"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v4.0.4","v4.0.3","v4.0.2","v4.0.1","v4.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-42297.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:H/SC:N/SI:H/SA:H"}]}
