Description
EdgeEver 1.6.0 through 1.112.0 contains a stored cross-site scripting vulnerability in TemplatesPane.tsx that renders template contentMarkdown with raw HTML via dangerouslySetInnerHTML without sanitization. Attackers can write templates containing HTML event handlers through an API or MCP token to run script on preview and access the privileged window.edgeeverDesktop bridge.
