{"id":"UBUNTU-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":"2026-08-07T17:45:16.265333794Z","published":"2026-07-17T21:17:00Z","upstream":["CVE-2026-54466"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-54466"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-54466"},{"type":"REPORT","url":"https://github.com/faye/websocket-driver-node/security/advisories/GHSA-xv26-6w52-cph6"}],"affected":[{"package":{"name":"node-websocket-driver","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/node-websocket-driver?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.3.5-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-websocket-driver","binary_version":"0.3.5-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54466.json"}},{"package":{"name":"node-websocket-driver","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/node-websocket-driver?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.3.5-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.3.5-1","binary_name":"node-websocket-driver"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54466.json"}},{"package":{"name":"node-websocket-driver","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/node-websocket-driver?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.3.5-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.3.5-1","binary_name":"node-websocket-driver"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54466.json"}},{"package":{"name":"node-websocket-driver","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/node-websocket-driver?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.7.4+~cs0.6.7-2"],"ecosystem_specific":{"binaries":[{"binary_name":"node-websocket-driver","binary_version":"0.7.4+~cs0.6.7-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54466.json"}},{"package":{"name":"node-websocket-driver","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/node-websocket-driver?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.7.4+~cs0.6.7-2"],"ecosystem_specific":{"binaries":[{"binary_name":"node-websocket-driver","binary_version":"0.7.4+~cs0.6.7-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54466.json"}},{"package":{"name":"node-websocket-driver","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/node-websocket-driver?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.7.4+~cs0.6.7-2","0.7.4+~cs0.6.14-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.7.4+~cs0.6.14-1","binary_name":"node-websocket-driver"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54466.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:H/SA:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}
