Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-31892 exists.\n\nAffected packages and fixed versions:\n- github.com/argoproj/argo-workflows (Go): affected all versions; no fix listed\n- github.com/argoproj/argo-workflows (Go): affected from 2.9.0; no fix listed\n- github.com/argoproj/argo-workflows (Go): affected from 2.9.0; no fix listed\n- argo-workflows (Bitnami): affected all versions; fixed in 3.7.11, 4.0.2\n- github.com/argoproj/argo-workflows/v2 (Go): affected from 2.9.0; no fix listed\n- github.com/argoproj/argo-workflows/v3 (Go): affected all versions; fixed in 3.7.11\n- github.com/argoproj/argo-workflows/v3 (Go): affected all versions; fixed in 3.7.11\n- github.com/argoproj/argo-workflows/v3 (Go): affected all versions; fixed in 3.7.11\n- github.com/argoproj/argo-workflows/v4 (Go): affected all versions; fixed in 4.0.2\n- github.com/argoproj/argo-workflows/v4 (Go): affected all versions; fixed in 4.0.2\n- github.com/argoproj/argo-workflows/v4 (Go): affected all versions; fixed in 4.0.2\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-31892/ (Markdown: https://insights.sbomify.com/CVE-2026-31892/index.md)","id":"CVE-2026-31892","markdown":"https://insights.sbomify.com/CVE-2026-31892/index.md","name":"CVE-2026-31892","record":{"aliases":["BIT-argo-workflows-2026-31892","ECHO-11ce-20c3-b91e","GHSA-3wf5-g532-rcrr","GO-2026-4681","MINI-4g5j-fgcr-vv5p","MINI-7fmc-rh5x-78p7","MINI-fmmh-3x65-6647","MINI-gx4c-c57m-fmpm","MINI-phw7-m59j-f8j5","MINI-rq9f-v6hh-m4w8","MINI-vqm7-qfg3-26h5","MINI-wph3-9354-ccq3","ROOT-APP-GOBINARY-CVE-2026-31892"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes workflow engine","requires_auth":"low_privilege","summary":"Attackers can bypass strict template security controls in Argo Workflows by injecting podSpecPatch, allowing unauthorized pod configuration changes.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"argo_workflows","vendor":"argoproj"}],"cvss":{"score":8.9,"severity":"high","source":"cna","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","version":"4.0"},"cwes":[{"id":"CWE-807","name":"Reliance on Untrusted Inputs in a Security Decision"},{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. From 2.9.0 to before 4.0.2 and 3.7.11, A user who can submit Workflows can completely bypass all security settings defined in a WorkflowTemplate by including a podSpecPatch field in their Workflow submission. This works even when the controller is configured with templateReferencing: Strict, which is specifically documented as a mechanism to restrict users to admin-approved templates. The podSpecPatch field on a submitted Workflow takes precedence over the referenced WorkflowTemplate during spec merging and is applied directly to the pod spec at creation time with no security validation.
