CVE-2025-25187
February 07, 2025
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 adding note titles to the document using React's "dangerouslySetInnerHTML", without first escaping HTML entities. Joplin lacks a Content-Security-Policy with a restrictive "script-src". This allows arbitrary JavaScript execution via inline "onclick"/"onload" event handlers in unsanitized HTML. Additionally, Joplin's main window is created with "nodeIntegration" set to "true", allowing arbitrary JavaScript execution to result in arbitrary code execution. Anyone who 1) receives notes from unknown sources and 2) uses <kbd>ctrl</kbd>-<kbd>p</kbd> to search is impacted. This issue has been addressed in version 3.1.24 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
