Description

Joplin is a free, open source note taking and to-do application, which can handle a large number of notes organised into notebooks. This vulnerability is caused by differences between how Joplin's HTML sanitizer handles comments and how the browser handles comments. This affects both the Rich Text Editor and the Markdown viewer. However, unlike the Rich Text Editor, the Markdown viewer is `cross-origin isolated`, which prevents JavaScript from directly accessing functions/variables in the toplevel Joplin `window`. This issue is not present in Joplin 3.1.24 and may have been introduced in `9b50539`. This is an XSS vulnerability that impacts users that open untrusted notes in the Rich Text Editor. This vulnerability has been addressed in version 3.2.12 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
