{"id":"CVE-2026-32608","aliases":["GHSA-vcv2-q258-wrg7","PYSEC-2026-2167"],"url":"https://o3.security/vulnerability/CVE-2026-32608","summary":"Glances has a Command Injection via Process Names in Action Command Templates","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.","published":"2026-03-18T06:03:22.153Z","modified":"2026-08-07T11:48:53.011069945Z","cvss":{"score":7,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"glances","fixedVersion":"4.5.2"}],"fix":{"url":"https://github.com/nicolargo/glances/commit/6f4ec53d967478e69917078e6f73f448001bf107","label":"nicolargo/glances@6f4ec53"},"references":[{"type":"WEB","url":"https://github.com/nicolargo/glances/releases/tag/v4.5.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32608.json"},{"type":"ADVISORY","url":"https://github.com/nicolargo/glances/security/advisories/GHSA-vcv2-q258-wrg7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32608"},{"type":"FIX","url":"https://github.com/nicolargo/glances/commit/6f4ec53d967478e69917078e6f73f448001bf107"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:48:53.011069945Z"}}
