CVE-2024-50581
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn JetBrains YouTrack before 2024.3.47707 improper HTML sanitization could lead to XSS attack via comment tag
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 · moderate confidenceCross-site scripting (XSS) vulnerability in JetBrains YouTrack's comment rendering due to improper HTML sanitization. Attackers can inject malicious JavaScript via specially crafted comment tags that bypass the sanitization filters, executing in victims' browser sessions when comments are viewed.

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.
-
Determine installed YouTrack versionAccess YouTrack admin area > About or check the version via the system information page. On self-hosted installations, you can also check the installation directory for version metadata or the startup logs.Affected if The installed version is lower than 2024.3.47707 (e.g., 2024.2.x, 2024.1.x, earlier versions)
-
Verify comment feature is enabledNavigate to YouTrack administration > Features > Comments or check project settings to confirm the comment module is active for any project.Affected if Comments are enabled and accessible to users in the system
-
Identify user roles with comment privilegesReview user roles and group permissions in YouTrack administration > Users & Security. Check which roles have 'Create comment' or 'Write' permissions on projects.Affected if Any user role other than fully trusted administrators can create comments
-
Inspect existing comments for unexpected contentBrowse recent comments in active projects, or use the search issue index with 'comment:*' to review comment content for any suspicious HTML or script tags.Affected if Malicious comments exist in the system that could have been injected
-
Check audit logs for comment creationReview YouTrack audit logs or activity logs for any unusual comment creation patterns from unexpected user accounts.Affected if There are recent comments created that you cannot attribute to known trusted users
You are affected if YouTrack version is below 2024.3.47707 AND the comment feature is accessible to users who are not fully trusted administrators.

dbcve · scoped2024.3.47707
Upgrade YouTrack to version 2024.3.47707 or later which contains the corrected HTML sanitization. Until patched, restrict comment creation privileges to trusted users only.
YouTrack 2024.3.47707 or later (2024.3 branch)
- Ensure you have a current backup of your YouTrack database and configuration
- Download YouTrack version 2024.3.47707 or later from the official JetBrains website (www.jetbrains.com/youtrack/download)
- Stop the YouTrack service before performing the upgrade
- Follow the standard YouTrack upgrade procedure: extract the new version to your installation directory, then run the database migration if prompted
- Start the YouTrack service after the upgrade completes
- Verify the upgrade was successful by logging in and checking the YouTrack version in Administration > Global Settings
- Test that comment functionality works correctly to confirm the XSS fix is applied
