CVSS: 7.7EPSS: 0%CPEs: 1EXPL: 0CVE-2024-49362 – Remote Code Execution on click of <a> Link in markdown preview
https://notcve.org/view.php?id=CVE-2024-49362
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') •
CVSS: 9.6EPSS: 0%CPEs: 1EXPL: 0CVE-2024-40643 – Joplin has a parsing error leading to Cross-site Scripting (XSS)
https://notcve.org/view.php?id=CVE-2024-40643
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 https://github.com/laurent22/joplin/security/advisories/GHSA-g796-3g6g-jmmc • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 8.2EPSS: 0%CPEs: 1EXPL: 0CVE-2023-37898 – Safe mode Cross-site Scripting (XSS) vulnerability in Joplin
https://notcve.org/view.php?id=CVE-2023-37898
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 <pre> and </pre>, without escaping any interior HTML tags. Thus, an attacker can create a note that closes the opening <pre> tag, then includes HTML that runs JavaScript. Because the rendered markdown iframe has the same origin as the toplevel document and is not sandboxed, any scripts running in the preview iframe can access the top variable and, thus, access the toplevel NodeJS `require` function. • https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe#sandbox https://github.com/laurent22/joplin/security/advisories/GHSA-hjmq-3qh4-g2r8 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 8.2EPSS: 0%CPEs: 1EXPL: 0CVE-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
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') •
CVSS: 8.2EPSS: 0%CPEs: 1EXPL: 0CVE-2023-39517 – Cross site scripting (XSS) when clicking on an untrusted `<map>` link in Joplin
https://notcve.org/view.php?id=CVE-2023-39517
Joplin is a free, open source note taking and to-do application. A Cross site scripting (XSS) vulnerability in affected versions allows clicking on an untrusted image link to execute arbitrary shell commands. The HTML sanitizer (`packages/renderer/htmlUtils.ts::sanitizeHtml`) preserves `<map>` `<area>` links. However, unlike `<a>` links, the `target` and `href` attributes are not removed. Additionally, because the note preview pane isn't sandboxed to prevent top navigation, links with `target` set to `_top` can replace the toplevel electron page. • https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe#sandbox https://github.com/laurent22/joplin/commit/7c52c3e9a81a52ef1b42a951f9deb9d378d59b0f https://github.com/laurent22/joplin/security/advisories/GHSA-2h88-m32f-qh5m • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
