Summary

CVE-2026-41363 is a medium-severity Path Traversal (CWE-22) vulnerability in Openclaw Openclaw. Its CVSS base score is 6.0 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 26th 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 2026.2.6 through 2026.3.24 contain a path traversal vulnerability in the Feishu extension resolveUploadInput function that bypasses file-system sandbox restrictions. Attackers can exploit improper path resolution during upload_image operations to read arbitrary files outside configured localRoots boundaries.

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?

Path traversal in upload_image directly enables arbitrary local file reads outside sandbox boundaries, mapping to Data from Local System.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly validates resolveUploadInput paths to reject traversal sequences before they bypass localRoots sandbox boundaries.

prevent

Enforces file-system access policy so upload_image operations cannot read outside the configured directory boundaries.

prevent

Mediates information flow to ensure data is never retrieved from locations outside the declared localRoots.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

detects

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
