Summary

CVE-2025-29631 is a critical-severity OS Command Injection (CWE-78) vulnerability in Mygardyn (inferred from references). Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 20% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

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.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Gardyn Home Kit firmware before master.619, the associated mobile application before version 2.11.0, and the cloud API before 2.12.2026 contain a command-injection flaw. The affected components fail to sanitize user-supplied input before passing it to operating-system execution routines, enabling arbitrary command execution on the target device. The issue is tracked under CWE-78 and CWE-94 and carries a CVSS 3.1 base score of 9.8.

An unauthenticated attacker with network access can supply crafted input through the vulnerable methods and obtain arbitrary operating-system command execution on an internet-exposed Home Kit. Successful exploitation grants full control over the device, including the ability to read or modify data and potentially pivot to other systems on the same network.

Vendor and government sources direct users to apply the referenced firmware, application, and API updates. The Gardyn security bulletin and the CISA advisory ICSA-26-055-03 provide the official remediation guidance and timelines. The EPSS score has remained flat at 0.02 with no material increase since disclosure.

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.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06 mostly match
prevents

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.

PR.PS-02 partial match
prevents

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).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

finds

Security testing and code review target insecure use of operating-system command interfaces, catching command-injection flaws introduced during development.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.
