Openclaw: >> Openclaw >> 2026.1.53 Security Vulnerabilities
OpenClaw before 2026.4.2 contains an improper trust boundary vulnerability allowing untrusted workspace channel shadows to execute during built-in channel setup and login. Attackers can clone a workspace with a malicious plugin claiming a bundled channel id to achieve unintended in-process code execution before the plugin is explicitly trusted.

OpenClaw Client PKCE Verifier Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose stored credentials on affected installations of OpenClaw. User interaction is required to exploit this vulnerability in that the target must initiate an OAuth authorization flow.
The specific flaw exists within the implementation of OAuth authorization. The issue results from the exposure of sensitive data in the authorization URL query string. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-29381.

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.
