CVE-2025-25187 is a high-severity flaw (CVSS 7.8) affecting joplin. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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 unsanitiz
Why this priority
- High severity
- Public exploit reference
A fixed release or distro patch exists.
