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.","cvss_v4":{"vector":"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","score":8.5},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:H","score":8.3},"cwes":["CWE-862","CWE-425"],"references":["https://github.com/argoproj/argo-workflows/commit/09fff05e0830c14a5e36cc40597ad84881db1ab6","https://github.com/argoproj/argo-workflows/releases/tag/v4.0.5","https://github.com/argoproj/argo-workflows/security/advisories/GHSA-xchc-cqwg-g76q","https://access.redhat.com/security/cve/CVE-2026-42297","https://bugzilla.redhat.com/show_bug.cgi?id=2468448"],"products":["argoproj:argo_workflows"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-42297","score":0.00515,"percentile":0.43892,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-xchc-cqwg-g76q","url":"https://osv.dev/vulnerability/GHSA-xchc-cqwg-g76q","summary":"Argo has Missing Authorization in its Sync ConfigMap Provider","modified":"2026-09-10T03:50:48.081823135Z","packages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-workflows/v4","purl":"pkg:golang/github.com/argoproj/argo-workflows/v4","ranges":[">=4.0.0 <4.0.5"],"fixed":["4.0.5"]}]},{"id":"GO-2026-5751","url":"https://osv.dev/vulnerability/GO-2026-5751","summary":"Argo has Missing Authorization in its Sync ConfigMap Provider in github.com/argoproj/argo-workflows","modified":"2026-07-02T14:44:24.914698799Z","packages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-workflows","purl":"pkg:golang/github.com/argoproj/argo-workflows","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/argoproj/argo-workflows/v2","purl":"pkg:golang/github.com/argoproj/argo-workflows/v2","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/argoproj/argo-workflows/v3","purl":"pkg:golang/github.com/argoproj/argo-workflows/v3","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/argoproj/argo-workflows/v4","purl":"pkg:golang/github.com/argoproj/argo-workflows/v4","ranges":[">=4.0.0 <4.0.5"],"fixed":["4.0.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
