{"id":"UBUNTU-CVE-2026-69185","details":"Socket.IO enables bidirectional and low-latency communication for every platform. Prior to 4.2.7, 3.4.5, and 3.3.6, a specially crafted Socket.IO packet can make the server wait for a large number of binary attachments and buffer them, which can be exploited to make the server run out of memory. This vulnerability is fixed in 4.2.7, 3.4.5, and 3.3.6.","modified":"2026-08-06T00:23:23Z","published":"2026-08-03T20:17:00Z","upstream":["CVE-2026-69185"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-69185"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-69185"},{"type":"REPORT","url":"https://github.com/socketio/socket.io/security/advisories/GHSA-2m8v-j782-fhvr"},{"type":"REPORT","url":"https://github.com/socketio/socket.io/commit/7c6ef571a00656718e9e05e3b948fd1758b2a7b4"},{"type":"REPORT","url":"https://github.com/socketio/socket.io/commit/9c6323e5cde41bd75df3379b5fc9293664a5f240"},{"type":"REPORT","url":"https://github.com/socketio/socket.io/commit/ced94ffa3ac020a8f3c14eb98a3bf34acb14d291"}],"affected":[{"package":{"name":"node-socket.io-parser","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/node-socket.io-parser?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.3.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-socket.io-parser","binary_version":"2.3.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-69185.json"}},{"package":{"name":"node-socket.io-parser","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/node-socket.io-parser?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.0-1","3.4.0-1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.4.0-1","binary_name":"node-socket.io-parser"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-69185.json"}},{"package":{"name":"node-socket.io-parser","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/node-socket.io-parser?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.0.2-1","4.1.1+~3.0.0-1","4.1.2+~3.0.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-socket.io-parser","binary_version":"4.1.2+~3.0.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-69185.json"}},{"package":{"name":"node-socket.io-parser","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/node-socket.io-parser?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.2.1+~3.1.0-3"],"ecosystem_specific":{"binaries":[{"binary_name":"node-socket.io-parser","binary_version":"4.2.1+~3.1.0-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-69185.json"}},{"package":{"name":"node-socket.io-parser","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/node-socket.io-parser?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.2.1+~3.1.0-3","4.2.1+~3.1.0-4"],"ecosystem_specific":{"binaries":[{"binary_name":"node-socket.io-parser","binary_version":"4.2.1+~3.1.0-4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-69185.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
