OpenClaw 2026.2.6 < 2026.2.14 Deep Link Message Truncation (macOS) (GHSA-7q2j-c4q5-rm27)

medium Nessus Plugin ID 299796

Synopsis

The remote macOS host is affected by a remote code execution vulnerability.

Description

The version of OpenClaw 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.

Solution

Upgrade to OpenClaw version 2026.2.14 or later.
