{"id":"UBUNTU-CVE-2025-13466","details":"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. An attacker can send payloads containing thousands of parameters within the default 100KB request size limit, causing elevated CPU and memory usage. This can lead to service slowdown or partial outages under sustained malicious traffic. This issue is addressed in version 2.2.1.","modified":"2026-05-20T16:20:22.788260219Z","published":"2025-11-24T19:15:00Z","upstream":["CVE-2025-13466"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-13466"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-13466"},{"type":"REPORT","url":"https://github.com/expressjs/body-parser/security/advisories/GHSA-wqch-xfxh-vrr4"}],"affected":[{"package":{"name":"node-body-parser","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/node-body-parser?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.8.1-1","binary_name":"node-body-parser"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-13466.json"}},{"package":{"name":"node-body-parser","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/node-body-parser?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.1-1","1.8.1-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.8.1-1ubuntu1","binary_name":"node-body-parser"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-13466.json"}},{"package":{"name":"node-body-parser","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/node-body-parser?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.18.3-2","1.19.0-2"],"ecosystem_specific":{"binaries":[{"binary_name":"node-body-parser","binary_version":"1.19.0-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-13466.json"}},{"package":{"name":"node-body-parser","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/node-body-parser?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.19.0-2","1.19.0-5","1.19.1+~1.19.2-1","1.19.2+~1.19.2-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.19.2+~1.19.2-1","binary_name":"node-body-parser"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-13466.json"}},{"package":{"name":"node-body-parser","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/node-body-parser?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.20.1+~1.19.2-1","1.20.2+~1.19.5-1","1.20.2+~1.19.5-1build2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.20.2+~1.19.5-1build2","binary_name":"node-body-parser"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-13466.json"}},{"package":{"name":"node-body-parser","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/node-body-parser?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.20.3+~1.19.5-3"],"ecosystem_specific":{"binaries":[{"binary_version":"1.20.3+~1.19.5-3","binary_name":"node-body-parser"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-13466.json"}},{"package":{"name":"node-body-parser","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/node-body-parser?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.20.3+~1.19.5-3","2.2.0+~1.19.6-1","2.2.2+~1.19.6-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.2.2+~1.19.6-1","binary_name":"node-body-parser"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-13466.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"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"},{"type":"Ubuntu","score":"medium"}]}
