Background

OpenClaw is an open-source application designed for managing and exporting session data. It allows users to generate HTML reports of their sessions, which can include various types of content. However, prior to version 2026.5.12, OpenClaw had a vulnerability that allowed unsafe links to be preserved in exported HTML, potentially leading to cross-site scripting (XSS) attacks.

Vulnerability Detail

The vulnerability arises from the way OpenClaw handles exported session HTML. Specifically, it fails to sanitize certain types of links, such as 'javascript:' and 'data:' links, which can be exploited by attackers. If a trusted user opens an exported file containing these malicious links, they may inadvertently execute harmful scripts in their browser. This vulnerability is classified under CWE-83, indicating an issue with improper neutralization of input during web page generation.

How To Fix

No fixed version is published for this vulnerability.

To fix this vulnerability, users should update OpenClaw to version 2026.5.12 or later. This can be done by running the following command in your terminal: 'npm install openclaw@latest'. This command will ensure that you have the patched version of the package that addresses the XSS vulnerability.

Workaround

As a temporary workaround, users can manually inspect exported HTML files for any unsafe links before opening them in a browser. Avoid clicking on any links that appear suspicious or contain 'javascript:' or 'data:' protocols.

Conclusion

The cross-site scripting vulnerability in OpenClaw highlights the importance of proper input sanitization in web applications. Users are encouraged to update to the latest version to mitigate risks and ensure the security of their exported session data.
