An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-71864 exists.\n\nAffected packages and fixed versions:\n- orval (npm): affected all versions; fixed in 8.21.0\n- orval (npm): affected all versions; fixed in 8.21.0\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-2026-71864/ (Markdown: https://insights.sbomify.com/CVE-2026-71864/index.md)","id":"CVE-2026-71864","markdown":"https://insights.sbomify.com/CVE-2026-71864/index.md","name":"CVE-2026-71864","record":{"aliases":["GHSA-6437-gxhq-pqv8","ROOT-APP-NPM-CVE-2026-71864"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenAPI client generator","requires_auth":"none","summary":"Attackers can execute arbitrary code in developer or CI environments by injecting JavaScript into generated client code via malicious OpenAPI header parameter names.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-95","name":"Improper Neutralization of Directives in Dynamically Evaluated Code"},{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. Prior to 8.21.0, a double quote in a header parameter name is emitted into the generated request-validation zod.object({...}) schema without safe encoding.
