CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2026-33641 is a high-severity OS Command Injection (CWE-78) vulnerability in Nicolargo Glances. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 44% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-33641 is an OS command injection vulnerability (CWE-78) in Glances, an open-source cross-platform system monitoring tool. In versions prior to 4.5.3, the Config.get_value() function processes dynamic configuration values by executing substrings enclosed in backticks as system commands without any validation or restrictions during configuration parsing.
A local attacker with low privileges (PR:L) who can modify or influence Glances configuration files can exploit this issue to execute arbitrary commands automatically with the privileges of the Glances process upon startup or configuration reload. If Glances is deployed with elevated privileges, such as running as a system service, successful exploitation enables privilege escalation, potentially granting high confidentiality, integrity, and availability impacts (C:H/I:H/A:H). The CVSS v3.1 base score is 7.8 (AV:L/AC:L/PR:L/UI:N/S:U).
The vulnerability has been patched in Glances version 4.5.3. Security practitioners should upgrade to this version for mitigation. Official resources include the GitHub security advisory at GHSA-qhj7-v7h7-q4c7, the patching commit 358d76a225fc21a9f95d2c4d7e46fafe64a644c6, and the release notes for v4.5.3.

Vulnerability Data
Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.3, Glances supports dynamic configuration values in which substrings enclosed in backticks are executed as system commands during configuration parsing. This behavior occurs in Config.get_value() and is implemented without…

validation or restriction of the executed commands. If an attacker can modify or influence configuration files, arbitrary commands will execute automatically with the privileges of the Glances process during startup or configuration reload. In deployments where Glances runs with elevated privileges (e.g., as a system service), this may lead to privilege escalation. This issue has been patched in version 4.5.3.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
