CVE-2026-3689 Details
Description
OpenClaw Canvas Path Traversal Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of OpenClaw. Authentication is required to exploit this vulnerability. The specific flaw exists within the handling of the path parameters provided to the canvas gateway endpoint. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to disclose information in the context of the service account. Was ZDI-CAN-29312.
A path traversal vulnerability allowing information disclosure has been identified in OpenClaw versions through 2026.2.19-2. This issue arises from improper validation of user-supplied path parameters in the canvas gateway endpoint, enabling authenticated remote attackers to read arbitrary files accessible to the gateway process. The extracted file contents are transmitted to the connected node client via a WebSocket command, potentially exposing sensitive information such as the gateway token.
OpenClaw has released a patch for this vulnerability. Users should update to version 2026.2.21 or later.
