{"id":"DEBIAN-CVE-2026-111181","details":"body-parser is body parsing middleware for Node.js and Express. In versions before 1.20.9 and in versions from 2.0.0 before 2.4.0, a single request can crash any application using body-parser with default options. When a request carries a Content-Encoding such as gzip, body-parser pipes it into a decompression stream and, after reading the body, leaves that stream with no error listener. A payload of one valid compressed frame followed by trailing bytes decodes and the application responds normally, but the trailing bytes then reach the already-finished decoder, which emits an error that is re-thrown as an uncaught exception and terminates the process. No matching route is required because body parsing runs before routing, so any endpoint that parses a body is affected. The issue is fixed in body-parser 2.4.0 and 1.20.9, and users should upgrade to one of those versions or later. As a workaround, disable request-body inflation (set the body-parser inflate option to false) so encoded requests are rejected before any decompression stream is created.","modified":"2026-10-26T08:00:08.541723590Z","published":"2026-10-22T15:17:04.763Z","upstream":["CVE-2026-111181"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-111181"}],"affected":[{"package":{"name":"node-body-parser","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-body-parser?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.20.1+~1.19.2-1","1.20.2+~1.19.5-1","1.20.3+~1.19.5-1","1.20.3+~1.19.5-2","1.20.3+~1.19.5-3","2.2.0+~1.19.6-1","2.2.0+~1.19.6-2","2.2.0+~1.19.6-3","2.2.1+~1.19.6-1","2.2.2+~1.19.6-1","2.3.0+~1.19.6-1","2.4.0+~1.19.6-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-111181.json"}},{"package":{"name":"node-body-parser","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-body-parser?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.20.3+~1.19.5-3","2.2.0+~1.19.6-1","2.2.0+~1.19.6-2","2.2.0+~1.19.6-3","2.2.1+~1.19.6-1","2.2.2+~1.19.6-1","2.3.0+~1.19.6-1","2.4.0+~1.19.6-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-111181.json"}},{"package":{"name":"node-body-parser","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-body-parser?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.0+~1.19.6-1"}]}],"versions":["1.20.3+~1.19.5-3","2.2.0+~1.19.6-1","2.2.0+~1.19.6-2","2.2.0+~1.19.6-3","2.2.1+~1.19.6-1","2.2.2+~1.19.6-1","2.3.0+~1.19.6-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-111181.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"}]}
