Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-5208 is a command injection vulnerability (CWE-78) in the alerts component of CoolerControl/coolercontrold versions prior to 4.0.0. It enables attackers to inject bash commands into alert names, leading to arbitrary code execution. The vulnerability carries a CVSS v3.1 base score of 8.2 (AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H), indicating high severity due to its potential for complete system compromise with low complexity but requiring local access and high privileges.
An authenticated attacker with high privileges on the affected system can exploit this vulnerability locally by crafting malicious alert names containing injected bash commands. Successful exploitation allows execution of arbitrary code with root privileges, potentially granting full control over the host system, including data exfiltration, persistence, or further lateral movement.
The vulnerability is demonstrated in the source code of version 3.1.0 at alerts.rs line 576 on the project's GitLab repository. Mitigation is available via upgrade to CoolerControl/coolercontrol version 4.0.0 or later, as announced in the corresponding release notes.

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).
