2026.2.14- Upgrade openclaw to this version or later
Description
Summary
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.
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.
Impact
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.
Affected Versions
- OpenClaw macOS desktop client versions >= 2026.2.6 and <= 2026.2.13.
Fixed Versions
- 2026.2.14.
Mitigations
- Do not approve unexpected "Run OpenClaw agent?" prompts triggered while browsing untrusted sites.
- Use unattended deep links only with a valid
keyfor trusted personal automations.
Resolution
Unkeyed deep links now enforce a strict message length limit for confirmation and ignore delivery/routing knobs (deliver, to, channel) unless a valid unattended key is provided.

How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-451: User Interface (UI) Misrepresentation of Critical Information
The user interface (UI) does not properly represent critical information to the user, allowing the information - or its source - to be obscured or spoofed. This is often a component in phishing attacks.
How to prevent it
- Implementation: Perform data validation (e.g. syntax, length, etc.) before interpreting the data.
- Architecture and Design: Create a strategy for presenting information, and plan for how to display unusual characters.
