{"id":"DEBIAN-CVE-2026-54465","details":"websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.8.1, when websocket-driver is used to implement a WebSocket server on top of a TCP server using WebSocket::Driver.server() or to complement a WebSocket client, a peer can make a single connection consume an unbounded amount of memory by sending an HTTP request or response with a never-ending list of headers. This can lead to the receiving process running out of memory. This issue is fixed in version 0.8.1.","modified":"2026-10-01T03:03:19.197482181Z","published":"2026-07-17T20:17:26.897Z","upstream":["CVE-2026-54465"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-54465"}],"affected":[{"package":{"name":"ruby-websocket-driver","ecosystem":"Debian:12","purl":"pkg:deb/debian/ruby-websocket-driver?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.6.3-3","0.8.0-1","0.8.1-1","0.8.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-54465.json"}},{"package":{"name":"ruby-websocket-driver","ecosystem":"Debian:13","purl":"pkg:deb/debian/ruby-websocket-driver?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.6.3-3","0.8.0-1","0.8.1-1","0.8.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-54465.json"}},{"package":{"name":"ruby-websocket-driver","ecosystem":"Debian:14","purl":"pkg:deb/debian/ruby-websocket-driver?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.8.1-1"}]}],"versions":["0.6.3-3","0.8.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-54465.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"}]}
