Description

Summary

The exported session HTML viewer allowed stored XSS when untrusted session content included raw HTML markdown tokens or unescaped metadata fields.

Impact

Opening a crafted exported HTML session could execute attacker-controlled JavaScript in the viewer context. This can expose session content in the page and enable phishing or UI spoofing in the trusted export view.

Affected Packages / Versions

Package: openclaw (npm)
Affected versions: <= 2026.2.22-2
Patched version (released): >= 2026.2.23

Technical Details

The exporter rendered markdown with marked.parse(...) and inserted HTML via innerHTML, but did not override the html renderer token path. Raw HTML (for example <img ... onerror=...>) was passed through. Additional tree/header metadata fields were interpolated without escaping in the export template.

Reproduction

Create a session containing content like <img src=x onerror=alert(1)>.
Export the session to HTML.
Open the exported file.
Observe script execution from injected content.

Remediation

Added a marked html(token) renderer override that escapes raw HTML tokens.
Escaped previously unescaped tree/header metadata fields in the export template.
Added image MIME sanitization for exported data-URL image rendering.
Added regression tests for markdown/token and metadata escaping paths.
