Summary

CVE-2026-32008 is a high-severity Externally Controlled Reference to a Resource in Another Sphere (CWE-610) vulnerability in Openclaw Openclaw. Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 33th 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 map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data

OpenClaw versions prior to 2026.2.21 contain an improper URL scheme validation vulnerability in the assertBrowserNavigationAllowed() function that allows authenticated users with browser-tool access to navigate to file:// URLs. Attackers can exploit this by accessing local files readable by the OpenClaw…

MITRE ATT&CK Enterprise TechniquesAI

T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
Why these techniques?

Improper file:// URL validation directly enables local file access and extraction by the browser tool, mapping to Data from Local System.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces the navigation policy inside assertBrowserNavigationAllowed() so that file:// URLs are rejected before any local-file access occurs.

prevent

Requires validation of URL scheme and origin on every browser navigation input, blocking the externally-controlled file:// reference that leads to data exfiltration.

prevent

Enforces information-flow rules that prevent the browser-tool from moving data from the file system into the snapshot/extraction channel used by the attacker.

PR.PS-06 mostly match
prevents

Secure development practices directly require input validation and reference sanitization that prevent externally-controlled resource references.

DE.CM-09 partial match
prevents

Runtime monitoring of software and data flows can detect anomalous external resource accesses that result from this weakness.

PR.IR-01 partial match
prevents

Network segmentation and access controls limit the blast radius when an external reference escapes its intended sphere.

detects

Security testing can detect instances of the weakness but does not prevent it at design or coding time.

prevents

Secure development lifecycle mandates validation of all external references to prevent uncontrolled resource access.

prevents

Application security requirements explicitly call for controls against externally supplied resource identifiers.

prevents

Secure architecture principles reduce the attack surface for externally controlled references but do not prescribe specific validation rules.

prevents

Secure coding standards require input validation and canonicalization to block externally controlled resource references.

mitigates

Information access restriction limits what resources can be reached, indirectly reducing impact of external references.
