Lifecycle Timeline
3DescriptionGitHub Advisory
OpenClaw is a personal AI assistant. OpenClaw macOS desktop client registers the openclaw:// URL scheme. For openclaw://agent deep links without an unattended key, the app shows a confirmation dialog that previously displayed only the first 240 characters of the message, but executed the full message after the user clicked "Run." At the time of writing, the OpenClaw macOS desktop client is still in beta. In versions 2026.2.6 through 2026.2.13, an attacker could pad the message with whitespace to push a malicious payload outside the visible preview, increasing the chance a user approves a different message than the one that is actually executed. If a user runs the deep link, the agent may perform actions that can lead to arbitrary command execution depending on the user's configured tool approvals/allowlists. This is a social-engineering mediated vulnerability: the confirmation prompt could be made to misrepresent the executed message. The issue is fixed in 2026.2.14. Other mitigations include not approve unexpected "Run OpenClaw agent?" prompts triggered while browsing untrusted sites and usingunattended deep links only with a valid key for trusted personal automations.
AnalysisAI
OpenClaw macOS desktop client versions 2026.2.6 through 2026.2.13 fail to fully display message content in confirmation dialogs for deep links, allowing attackers to hide malicious payloads behind whitespace that users cannot see before execution. When a user approves the truncated preview and clicks "Run," the full hidden message executes, potentially leading to arbitrary command execution depending on the user's configured permissions. This affects beta versions of the OpenClaw AI assistant on macOS where the openclaw:// URL scheme is registered without proper authentication.
