Prior to 3.7.15 and 4.0.6, the allow-list fix for CVE-2026-31892 is incomplete because workflow/util/merge.go ValidateUserOverrides and SanitizeUserWorkflowSpec walk only the top-level fields of WorkflowSpec via reflection, and WorkflowSpec.ArtifactGC is allow-listed wholesale; the struct behind that field, WorkflowLevelArtifactGC, has a PodSpecPatch sub-field whose contents flow unmodified into util.ApplyPodSpecPatch on the artifact-GC pod, the same sink the original fix closed for WorkflowSpec.PodSpecPatch, so a user submitting a Workflow under templateReferencing: Strict or Secure (against a referenced WorkflowTemplate that declares an output artifact and setting spec.artifactGC.strategy: OnWorkflowCompletion) can still inject an arbitrary strategic merge patch into the artifact-GC pod, including hostPath volumes, privileged: true, arbitrary image and command, and hostNetwork: true, defeating the stated purpose of Strict/Secure reference mode. This issue is fixed in versions 3.7.15 and 4.0.6.","state":0,"publishedAt":"2026-07-16T19:07:30.804+00:00","modifiedAt":"2026-07-17T13:57:43.413+00:00","affected":[{"ecosystem":"Vendor product","name":"argo-workflows","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"argoproj\",\n                    \"product\": \"argo-workflows\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.7.15\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 4.0.0, < 4.0.6\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:H/SI:H/SA:H","score":8.9,"severity":"HIGH"}],"references":["https://github.com/argoproj/argo-workflows/security/advisories/GHSA-48p8-g2fx-3wwm","https://github.com/argoproj/argo-workflows/commit/277e9cef0ad16d7eaaab253573d0695951a65dbd","https://github.com/argoproj/argo-workflows/commit/358cc3968c8f06f1be0967e41df191088db0b662","https://github.com/argoproj/argo-workflows/releases/tag/v3.7.15","https://github.com/argoproj/argo-workflows/releases/tag/v4.0.6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54526","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54526","identifiers":["CVE-2026-54526"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
