Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-93991 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- argo-workflows (Bitnami): affected from 4.1.0; fixed in 4.1.4\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-2026-93991/ (Markdown: https://insights.sbomify.com/CVE-2026-93991/index.md)","id":"CVE-2026-93991","markdown":"https://insights.sbomify.com/CVE-2026-93991/index.md","name":"CVE-2026-93991","record":{"aliases":["BIT-argo-workflows-2026-93991","GHSA-3fwg-9p8x-37mv","GHSA-q65w-j2vp-47c4","MINI-6hjf-wc65-6j94","MINI-gh54-75h2-5rmj","MINI-mjg7-h27f-vj5x","MINI-qf3j-34xf-cvc3"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Argo Workflows","requires_auth":"low_privilege","summary":"Attackers with namespace list permissions can bypass authorization to read archived workflows from other namespaces, exposing sensitive parameters and annotations.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"Argo Workflows versions 4.1.0 through 4.1.3 contain an authorization bypass vulnerability in ListArchivedWorkflows that fails to apply cluster-scoped access review when the metadata.namespace field selector uses the NotEquals operator.
