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.

OpenClaw Multiple Vulnerabilities February 20

The version of the OpenClaw AI assistant installed on the remote macOS host is 2026.2.6 or later but prior to 2026.2.14. It is, therefore, affected by a remote code execution vulnerability:

  - The 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 only displays the first 240 characters of the message but     executes the full message after the user clicks Run. 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. (CVE-2026-26320)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
