Attack-Flow Graph

Executive Summary

This vulnerability exists in OpenClaw versions before 2026.5.18 and involves an approval display truncation issue.

Authenticated users can exploit this by submitting oversized exec commands that have benign prefixes and malicious suffixes.

Because the approval display truncates the command, approvers only see the benign part and may unknowingly approve commands that contain hidden malicious operations.

Impact Analysis

The vulnerability can lead to unauthorized operations being executed after approval because malicious command suffixes are hidden from approvers.

This can result in a high impact on confidentiality, integrity, and availability of the affected system, as indicated by the high CVSS scores.
