How to Fix CVE-2018-1000534

To remediate this vulnerability, upgrade all affected Joplin dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

joplin fixed: 1.0.90
npm install joplin@1.0.90
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

npm ls joplin

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2018-1000534, inspect your project dependencies using npm:

npm ls joplin

Analyze the terminal output to locate any version of Joplin in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.90), your application is affected.

Note: The npm ls joplin command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Joplin, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Joplin version prior to 1.0.90 contains a Cross-site Scripting (XSS) evolving into code execution due to enabled nodeIntegration for that particular BrowserWindow instance where XSS was identified from vulnerability in Note content field - information on the fix can be found here https://github.com/laurent22/joplin/commit/494e235e18659574f836f84fcf9f4d4fcdcfcf89 that can result in executing unauthorized code within the rights in which the application is running. This attack appear to be exploitable via Victim synchronizing notes from the cloud services or other note-keeping services which contain malicious code. This vulnerability appears to have been fixed in 1.0.90 and later.
