{"id":"DEBIAN-CVE-2026-8162","details":"multiparty@4.2.3 and lower versions are vulnerable to denial of service via uncaught exception. By sending a multipart/form-data request with a Content-Disposition header whose filename* parameter contains a malformed percent-encoding, the parser invokes decodeURI on the value without try/catch. The resulting URIError propagates as an uncaught exception and crashes the process. Impact: any service accepting multipart uploads via multiparty is affected. Workarounds: none. Upgrade to multiparty@4.3.0 or higher.","modified":"2026-09-01T16:07:06.921695723Z","published":"2026-05-12T10:16:49.110Z","upstream":["CVE-2026-8162"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-8162"}],"affected":[{"package":{"name":"node-multiparty","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-multiparty?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.2.3-2","4.2.3-3","4.2.3-4","4.2.3-5","4.3.0+~4.2.1-1","4.3.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-8162.json"}},{"package":{"name":"node-multiparty","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-multiparty?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.2.3-3","4.2.3-4","4.2.3-5","4.3.0+~4.2.1-1","4.3.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-8162.json"}},{"package":{"name":"node-multiparty","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-multiparty?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3.0-1"}]}],"versions":["4.2.3-3","4.2.3-4","4.2.3-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-8162.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
