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.

EdgeEver through 1.112.0 contains a stored cross-site scripting vulnerability in setMemoDragPreview that allows attackers to inject script through notebook names or memo titles. Attackers can set malicious names via MCP createnotebook, renamenotebook or creatememo tools, running script on drag with access to the desktop bridge's session token.

EdgeEver through 1.108.0 contains a missing authorization vulnerability in the Hono API memo-template routes that allows holders of scoped API tokens to bypass token scope restrictions because template handlers never call requireScopes. Attackers with a token lacking write:memos can save a template and invoke POST /api/v1/templates/:id/use to create memos, and list, modify, or delete templates in the token owner's workspace.

EdgeEver 1.9.0 before 2.13.0 contains a stored cross-site scripting vulnerability in the backup restore endpoint PUT /api/v1/restores/json/resources/:id, which accepts a resource kind of image paired with a text/html MIME type without checking consistency. Authenticated members can share the note and send the public blob link to a victim, whose browser executes the script to mint a non-expiring API token granting read and write access to the victim's notes.
