{"id":"UBUNTU-CVE-2026-32608","details":"Glances is an open-source system cross-platform monitoring tool. The Glances action system allows administrators to configure shell commands that execute when monitoring thresholds are exceeded. These commands support Mustache template variables (e.g., `{{name}}`, `{{key}}`) that are populated with runtime monitoring data. The `secure_popen()` function, which executes these commands, implements its own pipe, redirect, and chain operator handling by splitting the command string before passing each segment to `subprocess.Popen(shell=False)`. Prior to 4.5.2, when a Mustache-rendered value (such as a process name, filesystem mount point, or container name) contains pipe, redirect, or chain metacharacters, the rendered command is split in unintended ways, allowing an attacker who controls a process name or container name to inject arbitrary commands. Version 4.5.2 fixes the issue.","modified":"2026-05-20T16:25:21.249389025Z","published":"2026-03-18T07:16:00Z","upstream":["CVE-2026-32608"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-32608"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-32608"},{"type":"REPORT","url":"https://github.com/nicolargo/glances/security/advisories/GHSA-vcv2-q258-wrg7"},{"type":"REPORT","url":"https://github.com/nicolargo/glances/commit/6f4ec53d967478e69917078e6f73f448001bf107"}],"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-2026-32608.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-2026-32608.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-2026-32608.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-2026-32608.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-2026-32608.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-2026-32608.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-2026-32608.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
