CVE-2026-53841 Details
Description
OpenClaw before 2026.5.12 contains a cross-site scripting vulnerability in exported session HTML that preserves unsafe javascript: and data: links in generated content. Attackers can execute browser-side scripts if a trusted operator opens the exported file and activates a malicious link.
A cross-site scripting vulnerability has been identified in OpenClaw versions prior to 2026.5.12. This issue arises in exported session HTML, which can retain unsafe 'javascript:' and 'data:' links. If a trusted operator opens the exported file and clicks on a malicious link, it could execute scripts in the browser.
Users are advised not to open exported session HTML from untrusted sources in a privileged browser profile until after updating to version 2026.5.12. As a general precaution, keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not needed.
