Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceReflected XSS vulnerability in JetBrains YouTrack versions before 2024.3.47707 allows attackers to inject malicious scripts through insecurely sanitized links. The vulnerability is triggered when a user clicks on a crafted malicious link, causing the payload to be reflected back and executed in the victim's browser context.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed YouTrack versionAccess the YouTrack administration interface and navigate to About (typically at /admin/about) or check the version using the command line if you have server access. The version number is displayed on the About page.Affected if The installed version is lower than 2024.3.47707 (for example, 2024.2.12345 or any version in the 2024.1.x, 2023.x, or earlier series).
-
Confirm YouTrack is accessible to external usersVerify that YouTrack is exposed to the network and users can access it via a web browser. Check if external users or untrusted parties can submit links or interact with the system.Affected if YouTrack is internet-facing or allows untrusted users to submit content containing links that other users might click.
-
Check for link handling in workflows or integrationsReview any custom workflows, REST API endpoints, or integrations that accept user-supplied URLs and display them back to users. Look for places where links are rendered in issue descriptions, comments, or notifications.Affected if Users can create or modify content that includes clickable links visible to other users (this is typical YouTrack usage).
A user is affected if their installed YouTrack version is below 2024.3.47707 and the system allows users to click on links submitted by others (standard usage).
