CVE-2025-25187

Summary

CVE-2025-25187 is a vulnerability affecting Joplin, a free and open source note-taking application. The issue arises when the application uses React's `dangerouslySetInnerHTML` to add note titles without proper HTML entity escaping. Malicious HTML code can be injected, leading to arbitrary JavaScript execution due to Joplin's weak Content-Security-Policy and the use of `nodeIntegration` set to `true` in its main window. This vulnerability can impact users who receive unsanitized notes and use the ctrl-p shortcut to search. Version 3.1.24 addresses this issue, and all users are advised to upgrade as there are currently no known workarounds.
