Summary

CVE-2026-8112 is a low-severity Command Injection (CWE-77) vulnerability in 8421Bit Miniclaw. Its CVSS base score is 2.1 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 14% 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.

Deeper analysis AI-assisted summary

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

A vulnerability exists in 8421bit MiniClaw up to commit 223c16a1088e138838dcbd18cd65a37c35ac5a84 that allows OS command injection through the executeCognitivePulse function in src/kernel.ts. The issue stems from improper handling of input that reaches operating system command execution paths, corresponding to CWE-77 and CWE-78. The product follows a rolling release model, so no discrete version numbers are tracked for affected or fixed releases. The CVSS 4.0 base score is 2.1 with network attack vector and low attack complexity.

An authenticated remote attacker can supply crafted input to trigger command injection and obtain limited control over the host operating system. The attack requires no user interaction and can be launched over the network. A public exploit for the flaw has been disclosed.

The repository contains a patch in commit 028f62216dee9f64833d0f1cfda7c217067ceba8 that addresses the command injection. The project maintainers recommend deploying this patch to resolve the issue, with related details available in the associated GitHub issue and pull request.

The EPSS score rose from a low baseline to a peak of 0.0123 on 2026-05-13 before receding to the current value of 0.0011, indicating a temporary increase in exploitation interest after public disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover command-construction flaws before deployment.

Input validation directly stops construction of commands from untrusted data containing special elements.

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 include proper neutralization and safe command construction practices.

prevents

Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.

finds

Security testing in development catches command-injection vulnerabilities before release.

prevents

Secure development life cycle mandates input validation and command construction practices that directly prevent command injection.

prevents

Application security requirements explicitly call for controls against injection flaws including command injection.

prevents

Secure architecture principles reduce the attack surface but do not prescribe the specific neutralization techniques needed.

none

Environment separation limits the blast radius of an exploited command injection but does not prevent the flaw itself.
