{"id":"PYSEC-2026-2167","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.","aliases":["CVE-2026-32608","GHSA-vcv2-q258-wrg7"],"modified":"2026-07-13T07:15:31.492684142Z","published":"2026-03-18T07:16:21.447Z","references":[{"type":"ADVISORY","url":"https://github.com/nicolargo/glances/releases/tag/v4.5.2"},{"type":"FIX","url":"https://github.com/nicolargo/glances/commit/6f4ec53d967478e69917078e6f73f448001bf107"},{"type":"EVIDENCE","url":"https://github.com/nicolargo/glances/security/advisories/GHSA-vcv2-q258-wrg7"}],"affected":[{"package":{"name":"glances","ecosystem":"PyPI","purl":"pkg:pypi/glances"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.5.2"}]}],"versions":["1.3.1","1.3.2","1.3.3","1.3.4","1.3.5","1.3.6","1.3.7","1.4","1.4.1","1.4.1.1","1.4.2","1.4.2.1","1.5","1.5.1","1.5.2","1.6","1.6.1","1.7","1.7.1","1.7.2","1.7.3","1.7.4","1.7.5","1.7.6","1.7.7","2.0","2.0.1","2.1","2.1.1","2.1.2","2.10","2.11","2.11.1","2.2","2.2.1","2.3","2.4","2.4.1","2.4.2","2.5","2.5.1","2.6","2.6.1","2.6.2","2.7","2.7.1","2.8","2.8.1","2.8.2","2.8.3","2.8.4","2.8.5","2.8.6","2.8.7","2.8.8","2.9.0","2.9.1","3.0","3.0.1","3.0.2","3.1.0","3.1.1","3.1.2","3.1.3","3.1.4","3.1.4.1","3.1.5","3.1.6","3.1.6.1","3.1.6.2","3.1.7","3.2.0","3.2.1","3.2.2","3.2.3","3.2.3.1","3.2.4","3.2.4.1","3.2.4.2","3.2.5","3.2.6.1","3.2.6.2","3.2.6.3","3.2.6.4","3.2.7","3.3.0","3.3.0.1","3.3.0.2","3.3.0.3","3.3.0.4","3.3.1","3.3.1.1","3.4.0","3.4.0.1","3.4.0.2","3.4.0.3","3.4.0.4","3.4.0.5","4.0.1","4.0.2","4.0.3","4.0.4","4.0.5","4.0.6","4.0.7","4.0.8","4.1.0","4.1.1","4.1.2","4.2.0","4.2.1","4.3.0","4.3.0.1","4.3.0.3","4.3.0.4","4.3.0.5","4.3.0.6","4.3.0.7","4.3.0.8","4.3.1","4.3.2","4.3.3","4.4.0","4.4.1","4.5.0","4.5.0.1","4.5.0.2","4.5.0.3","4.5.0.4","4.5.0.5","4.5.1"],"ecosystem_specific":{},"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/glances/PYSEC-2026-2167.yaml"}}],"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"}]}
