{"id":"UBUNTU-CVE-2026-55768","details":"GoAccess is a real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems or through the browser. Prior to version 1.11, the built-in WebSocket server narrows a 64-bit extended frame length into the signed 32-bit WSFrame.payloadlen field before enforcing the maximum frame size, allowing an unauthenticated remote client to bypass the guard and force an approximately 18-exabyte allocation request that terminates the process. This issue is fixed in version 1.11.","modified":"2026-08-06T03:10:21.145559761Z","published":"2026-07-30T21:17:00Z","upstream":["CVE-2026-55768"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-55768"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-55768"}],"affected":[{"package":{"name":"goaccess","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/goaccess?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:0.8.3-1","1:0.9.4-1","1:0.9.4-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"goaccess","binary_version":"1:0.9.4-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-55768.json"}},{"package":{"name":"goaccess","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/goaccess?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:1.2-3"],"ecosystem_specific":{"binaries":[{"binary_name":"goaccess","binary_version":"1:1.2-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-55768.json"}},{"package":{"name":"goaccess","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/goaccess?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:1.2-4","1:1.3-1"],"ecosystem_specific":{"binaries":[{"binary_name":"goaccess","binary_version":"1:1.3-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-55768.json"}},{"package":{"name":"goaccess","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/goaccess?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:1.4-1","1:1.5.1-1","1:1.5.1-1build1","1:1.5.5-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1:1.5.5-1","binary_name":"goaccess"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-55768.json"}},{"package":{"name":"goaccess","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/goaccess?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:1.7-1","1:1.8.1-1","1:1.8.1-1build1","1:1.8.1-1build2","1:1.8.1-1build3"],"ecosystem_specific":{"binaries":[{"binary_name":"goaccess","binary_version":"1:1.8.1-1build3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-55768.json"}},{"package":{"name":"goaccess","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/goaccess?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:1.9.3-1","1:1.9.3-1build1","1:1.9.4-1"],"ecosystem_specific":{"binaries":[{"binary_name":"goaccess","binary_version":"1:1.9.4-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-55768.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:N/VA:H/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
