CVE-2026-32040: OpenClaw Vulnerable to HTML injection via unvalidated image MIME type in data-URL interpolation
(updated )
The HTML session exporter (src/auto-reply/reply/export-html/template.js) interpolates img.mimeType directly into <img src="data:..."> attributes without validation or escaping. A crafted mimeType value (e.g., x" onerror="alert(1)) can break out of the attribute context and execute arbitrary JavaScript.
