{"id":"DEBIAN-CVE-2025-55702","details":"When a client sends a POST with Expect: 100-continue and the origin answers before reading the body, Apache Traffic Server parses the unread body left on the client connection as the next request. An attacker behind a front-end proxy that shares connections to Traffic Server can use this to smuggle requests past the front end and desynchronize responses for other users.    This issue affects Apache Traffic Server: from 8.0.0 through 8.1.11, from 9.0.0 through 9.2.15, from 10.0.0 through 10.1.4, 10.2.0.    Users are recommended to upgrade to version 9.2.16, 10.1.5, or 10.2.1, which fix the issue.","modified":"2026-10-22T05:00:05.722757346Z","published":"2026-10-21T19:47:27.490379656Z","upstream":["CVE-2025-55702"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-55702"}],"affected":[{"package":{"name":"trafficserver","ecosystem":"Debian:12","purl":"pkg:deb/debian/trafficserver?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.2.0+ds-2","9.2.0+ds-2+deb12u1","9.2.1+ds-1","9.2.2+ds-1","9.2.3+ds-1","9.2.3+ds-1+deb12u1","9.2.4+ds-0+deb12u1","9.2.4+ds-1","9.2.4+ds-2","9.2.5+ds-0+deb12u1","9.2.5+ds-0+deb12u2","9.2.5+ds-0+deb12u3","9.2.5+ds-0+deb12u4","9.2.5+ds-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-55702.json"}}],"schema_version":"1.9.0"}
