{"id":"UBUNTU-CVE-2026-46608","details":"Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.5, the Glances XML-RPC server (glances -s) introduced a configurable CORS origin list in version 4.5.3 as a mitigation for CVE-2026-33533. However, the implementation silently falls back to Access-Control-Allow-Origin: * whenever cors_origins contains more than one entry. An operator who configures an explicit two-entry allowlist (e.g. two internal dashboard origins) intending to restrict browser access instead receives the unrestricted wildcard. A malicious web page served from any origin can issue a CORS simple request to /RPC2 and read the full system monitoring dataset without the victim's knowledge. This vulnerability is fixed in 4.5.5.","modified":"2026-06-29T23:15:40.799062119Z","published":"2026-06-25T19:16:00Z","upstream":["CVE-2026-46608"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-46608"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-46608"},{"type":"REPORT","url":"https://github.com/nicolargo/glances/security/advisories/GHSA-87qc-fj39-wccr"}],"affected":[{"package":{"name":"glances","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/glances?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.3-1build1","2.3-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"glances","binary_version":"2.3-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-46608.json"}},{"package":{"name":"glances","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/glances?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.10-2","2.11.1-1","2.11.1-2","2.11.1-3","2.11.1-3ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.11.1-3ubuntu0.1~esm1","binary_name":"glances"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-46608.json"}},{"package":{"name":"glances","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/glances?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.0-1","3.1.1-1","3.1.3-1","3.1.3-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"glances","binary_version":"3.1.3-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-46608.json"}},{"package":{"name":"glances","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/glances?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.5-1","3.2.3.1+dfsg-1","3.2.4.2+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"glances","binary_version":"3.2.4.2+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-46608.json"}},{"package":{"name":"glances","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/glances?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.0.3+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.4.0.3+dfsg-1","binary_name":"glances"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-46608.json"}},{"package":{"name":"glances","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/glances?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.3.0.8+dfsg-1","4.3.1+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"glances","binary_version":"4.3.1+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-46608.json"}},{"package":{"name":"glances","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/glances?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.3.1+dfsg-1","4.3.3+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"glances","binary_version":"4.3.3+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-46608.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
