Summary

CVE-2026-28456 is a high-severity Uncontrolled Search Path Element (CWE-427) vulnerability in Openclaw Openclaw. Its CVSS base score is 8.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 32.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 AC-6 (Least Privilege) and CM-5 (Access Restrictions for Change).

Deeper analysis

CVE-2026-28456 is a vulnerability in the Gateway component of OpenClaw versions 2026.1.5 prior to 2026.2.14. The issue stems from insufficient constraints on configured hook module paths before they are passed to the dynamic import() function in the Node.js process, allowing arbitrary code execution. Classified as CWE-427 (Uncontrolled Search Path Element), it carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) and was published on 2026-03-05.

An attacker with access to modify the gateway configuration can exploit this flaw to load and execute unintended local modules in the Node.js process. Successful exploitation enables high-impact compromise of confidentiality, integrity, and availability within the Gateway, potentially leading to full control over the affected process.

Mitigation involves updating to OpenClaw version 2026.2.14 or later, as detailed in the GitHub security advisory GHSA-v6c6-vqqg-w888 and fixing commits such as 35c0e66ed057f1a9f7ad2515fdcef516bd6584ce and a0361b8ba959e8506dc79d638b6e6a00d12887e4.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.007 JavaScript Execution
Adversaries may abuse various implementations of JavaScript for execution.
Why these techniques?

The CVE describes an RCE flaw in a network-exposed Gateway component (AV:N) via unsafe dynamic import() of attacker-controlled Node.js modules after config modification, directly enabling exploitation of public-facing apps (T1190) followed by arbitrary JavaScript execution (T1059.007).

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Restricts access to modify gateway configuration settings such as hook module paths, directly blocking the prerequisite attacker capability.

prevent

Enforces least privilege on configuration modification rights so only authorized roles can alter hook module paths.

prevent

Requires validation of configured module paths before they are passed to dynamic import(), mitigating the uncontrolled search path element.
