{"id":"DEBIAN-CVE-2026-54466","details":"websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.7.5, the frame format in draft versions of the WebSocket protocol includes a length header that allows an arbitrarily large integer to be encoded as a sequence of bytes with the high bit set. By sending an indefinite sequence of bytes with values 0x80 or above, a client can make the server parse these bytes into an ever-growing integer in lib/websocket/driver/draft75.js; because JavaScript numbers are 64-bit floating point values, this number will eventually lose precision and lead to the subsequent payload being parsed incorrectly. This issue is fixed in version 0.7.5.","modified":"2026-09-29T13:04:03.241824341Z","published":"2026-07-17T21:17:08.657Z","upstream":["CVE-2026-54466"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-54466"}],"affected":[{"package":{"name":"node-websocket-driver","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-websocket-driver?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.7.4+~cs0.6.14-1","0.7.4+~cs0.6.7-2","0.7.5+~cs0.6.14-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-54466.json"}},{"package":{"name":"node-websocket-driver","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-websocket-driver?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.7.4+~cs0.6.14-1","0.7.4+~cs0.6.7-2","0.7.5+~cs0.6.14-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-54466.json"}},{"package":{"name":"node-websocket-driver","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-websocket-driver?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.7.5+~cs0.6.14-1"}]}],"versions":["0.7.4+~cs0.6.14-1","0.7.4+~cs0.6.7-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-54466.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:H/A:N"}]}
