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-2026-42297 exists.\n\nAffected packages and fixed versions:\n- github.com/argoproj/argo-workflows/v4 (Go): affected from 4.0.0; fixed in 4.0.5\n- github.com/argoproj/argo-workflows/v4 (Go): affected from 4.0.0; fixed in 4.0.5\n- github.com/argoproj/argo-workflows/v4 (Go): affected from 4.0.0; fixed in 4.0.5\n- argo-workflows (Bitnami): affected from 4.0.0; fixed in 4.0.5\n- github.com/argoproj/argo-workflows (Go): affected all versions; no fix listed\n- github.com/argoproj/argo-workflows/v2 (Go): affected all versions; no fix listed\n- github.com/argoproj/argo-workflows/v3 (Go): affected all versions; no fix listed\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-2026-42297/ (Markdown: https://insights.sbomify.com/CVE-2026-42297/index.md)","id":"CVE-2026-42297","markdown":"https://insights.sbomify.com/CVE-2026-42297/index.md","name":"CVE-2026-42297","record":{"aliases":["BIT-argo-workflows-2026-42297","GHSA-xchc-cqwg-g76q","GO-2026-5751","MINI-38h2-2289-xq7x","MINI-4526-5rf6-q3hm","MINI-5mpm-qhqg-84hg","MINI-85g5-w3hr-677g","MINI-cqgh-jrwp-rr97","MINI-gqmp-pp4q-ph9x","MINI-j952-cmvg-jx8r","MINI-q7gr-rh85-hh8g","MINI-vm5c-p9q4-5m8r","MINI-vpp2-rj25-mhph","MINI-x625-8776-3hpv","MINI-x829-4h7x-jw89"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes workflow engine","requires_auth":"low_privilege","summary":"Authenticated users can bypass authorization to create, read, update, or delete Kubernetes ConfigMaps in Argo Workflows.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"argo_workflows","vendor":"argoproj"}],"cvss":{"score":8.5,"severity":"high","source":"cna","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","version":"4.0"},"cwes":[{"id":"CWE-425","name":"Direct Request"},{"id":"CWE-862","name":"Missing Authorization"}],"description":"Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes.
