An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-13466 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- body-parser (npm): affected from 2.2.0; fixed in 2.2.1\n- body-parser (npm): affected from 2.2.0; fixed in 2.2.1\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-2025-13466/ (Markdown: https://insights.sbomify.com/CVE-2025-13466/index.md)","id":"CVE-2025-13466","markdown":"https://insights.sbomify.com/CVE-2025-13466/index.md","name":"CVE-2025-13466","record":{"aliases":["CLEANSTART-2026-SS80310","DEBIAN-CVE-2025-13466","GHSA-wqch-xfxh-vrr4","MINI-hfpq-8vmj-5px2","MINI-mg9m-mm9c-mr2r","MINI-rpgf-xhrq-jcc8","ROOT-APP-NPM-CVE-2025-13466","UBUNTU-CVE-2025-13466"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js body parser","requires_auth":"none","summary":"An attacker can cause denial of service in applications using body-parser by sending URL-encoded requests with excessive parameters, leading to resource exhaustion.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openjs","cpe":[],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:L/E:P/AU:Y","version":"4.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"body-parser 2.2.0 is vulnerable to denial of service due to inefficient handling of URL-encoded bodies with very large numbers of parameters.
