Summary

CVE-2026-1066 is a medium-severity Injection (CWE-74) vulnerability in Kodcloud Kodbox. Its CVSS base score is 5.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 8% 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.

A vulnerability has been identified in kalcaddle kodbox versions up to 1.61.10 within the Compression Handler component. The issue resides in the processing of the /?explorer/index/zip endpoint, where improper handling of input enables command injection, tracked under CWE-74 and CWE-77. The flaw is remotely exploitable with a CVSS 4.0 score of 5.3 reflecting limited impacts on confidentiality, integrity, and availability when low-privileged access is present.

An attacker with network access and low privileges can supply crafted input to the affected endpoint, resulting in arbitrary command execution on the server. The vendor was notified prior to disclosure but provided no response, and a public exploit is now available that demonstrates the injection.

The associated EPSS score started low after the January 2026 publication, rose materially to a peak of 0.0174 on 2026-02-18, and has since receded to 0.0006, indicating a temporary increase in exploitation interest following public release of the proof-of-concept. No vendor patches or official mitigation guidance appear in the referenced disclosures.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

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

SI-10 Information Input Validation good match

SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles include proper neutralization and safe command construction practices.

A.8.28 Secure coding mostly match
prevents

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

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development catches injection vulnerabilities before release.

A.8.15 Logging partial match
finds

Logging supports detection of injection attempts but does not prevent the weakness.

A.8.16 Monitoring activities partial match
finds

Monitoring activities can identify active injection attacks after they occur.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and output encoding that directly prevent injection flaws.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls against injection attacks in software design.
