Cross-site Scripting (XSS)

@joplin/renderer is a renderer used by Joplin to render notes in Markdown or HTML format.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS) due to insufficient sanitization in the sanitizeHtml() function. An attacker can execute shell commands by spinning up a local server that serves a page with malicious scripts and convincing a user to follow a malicious link from a note whose contents includes a <map> or <area> element pointing to the malicious site.

How to fix Cross-site Scripting (XSS)?

Upgrade @joplin/renderer to version 2.12.1 or higher.
