CVE-2025-25187 – Cross-site Scripting in Goto Anything allows arbitrary code execution in Joplin

https://notcve.org/view.php?id=CVE-2025-25187

07 Feb 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 `n... • https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/script-src • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

CVE-2024-55630 – DOM Clobbering leads to temporary DOS in the note viewer in Joplin

https://notcve.org/view.php?id=CVE-2024-55630

07 Feb 2025 — Joplin is a free, open source note taking and to-do application, which can handle a large number of notes organised into notebooks. Joplin's HTML sanitizer allows the `name` attribute to be specified. If `name` is set to the same value as an existing `document` property (e.g. `querySelector`), that property is replaced with the element. This vulnerability's only known impact is denial of service. • https://en.wikipedia.org/wiki/DOM_clobbering • CWE-20: Improper Input Validation •

CVE-2024-53268 – Lack of validation on openExternal allows 1 click remote code execution in joplin

https://notcve.org/view.php?id=CVE-2024-53268

25 Nov 2024 — Joplin is an open source, privacy-focused note taking app with sync capabilities for Windows, macOS, Linux, Android and iOS. In affected versions attackers are able to abuse the fact that openExternal is used without any filtering of URI schemes to obtain remote code execution in Windows environments. This issue has been addressed in version 3.0.3 and all users are advised to upgrade. There are no known workarounds for this vulnerability. • https://github.com/laurent22/joplin/security/advisories/GHSA-pc5v-xp44-5mgv • CWE-94: Improper Control of Generation of Code ('Code Injection') •

CVE-2024-49362 – Remote Code Execution on click of <a> Link in markdown preview

https://notcve.org/view.php?id=CVE-2024-49362

14 Nov 2024 — Joplin is a free, open source note taking and to-do application. Joplin-desktop has a vulnerability that leads to remote code execution (RCE) when a user clicks on an <a> link within untrusted notes. The issue arises due to insufficient sanitization of <a> tag attributes introduced by the Mermaid. This vulnerability allows the execution of untrusted HTML content within the Electron window, which has full access to Node.js APIs, enabling arbitrary shell command execution. • https://github.com/laurent22/joplin/security/advisories/GHSA-hff8-hjwv-j9q7 • CWE-94: Improper Control of Generation of Code ('Code Injection') •

CVE-2024-40643 – Joplin has a parsing error leading to Cross-site Scripting (XSS)

https://notcve.org/view.php?id=CVE-2024-40643

09 Sep 2024 — Joplin is a free, open source note taking and to-do application. Joplin fails to take into account that "<" followed by a non letter character will not be considered html. As such it is possible to do an XSS by putting an "illegal" tag within a tag. • https://github.com/laurent22/joplin/commit/b220413a9b5ed55fb1f565ac786a5c231da8bc87 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

CVE-2023-37898 – Safe mode Cross-site Scripting (XSS) vulnerability in Joplin

https://notcve.org/view.php?id=CVE-2023-37898

21 Jun 2024 — Joplin is a free, open source note taking and to-do application. A Cross-site Scripting (XSS) vulnerability allows an untrusted note opened in safe mode to execute arbitrary code. `packages/renderer/MarkupToHtml.ts` renders note content in safe mode by surrounding it with

 and 

, without escaping any interior HTML tags. Thus, an attacker can create a note that closes the opening

 tag, then includes HTML that runs JavaScript. Because the rendered markdown iframe has the same origin as the topl... • https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe#sandbox • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') • 

CVE-2023-38506 – Cross-site Scripting (XSS) when pasting HTML into the rich text editor in Joplin

https://notcve.org/view.php?id=CVE-2023-38506

21 Jun 2024 — Joplin is a free, open source note taking and to-do application. A Cross-site Scripting (XSS) vulnerability allows pasting untrusted data into the rich text editor to execute arbitrary code. HTML pasted into the rich text editor is not sanitized (or not sanitized properly). As such, the `onload` attribute of pasted images can execute arbitrary code. Because the TinyMCE editor frame does not use the `sandbox` attribute, such scripts can access NodeJS's `require` through the `top` variable. • https://github.com/laurent22/joplin/security/advisories/GHSA-m59c-9rrj-c399 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

CVE-2023-45673 – Arbitrary code execution on click of PDF links in Joplin

https://notcve.org/view.php?id=CVE-2023-45673

21 Jun 2024 — Joplin is a free, open source note taking and to-do application. A remote code execution (RCE) vulnerability in affected versions allows clicking on a link in a PDF in an untrusted note to execute arbitrary shell commands. Clicking links in PDFs allows for arbitrary code execution because Joplin desktop: 1. has not disabled top redirection for note viewer iframes, and 2. and has node integration enabled. This is a remote code execution vulnerability that impacts anyone who attaches untrusted PDFs to notes a... • https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe#sandbox • CWE-94: Improper Control of Generation of Code ('Code Injection') •
