OpenClaw macOS Client Truncates Confirmation, Hides Malicious Payload
CVE-2026-26320
GHSA-7q2j-c4q5-rm27
Summary
The OpenClaw macOS desktop client can display a misleading confirmation message when a user is asked to run a deep link. This could trick users into approving a different message than the one that is actually executed. To stay safe, be cautious when approving prompts from unknown sources and only use trusted, unattended deep links with a valid key for automated tasks.
What to do
- Update steipete openclaw to version 2026.2.14.
Affected software
| Vendor | Product | Affected versions | Fix available |
|---|---|---|---|
| steipete | openclaw | > 2026.2.6-0 , <= 2026.2.14 | 2026.2.14 |
| openclaw | openclaw | > 2026.2.6 , <= 2026.2.14 | – |
Original title
OpenClaw macOS deep link confirmation truncation can conceal executed agent message
Original 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 `key` for 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.
