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 confidenceA Cross-Site Request Forgery (CSRF) vulnerability was identified in an admin endpoint of JetBrains YouTrack. This allows an attacker to trick an authenticated administrator into unknowingly executing unintended administrative actions via maliciously crafted requests.

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 YouTrack versionAccess the YouTrack administration interface and navigate to 'About' or check the version through the API endpoint /api/admin/version, or locate the youtrack JAR file and inspect its version metadataAffected if The displayed version number is lower than 2018.4.49852
-
Verify admin endpoint accessibilityConfirm that the YouTrack admin interface (typically at /admin or /dashboard) is accessible over the network and does not require additional authentication layers beyond YouTrack's standard loginAffected if Admin endpoints are reachable by authenticated users without additional CSRF protection measures in place
-
Check for active admin sessionsReview the YouTrack audit logs or session management interface to identify active administrator sessions that could be targeted via CSRFAffected if There are active administrative sessions that could be exploited through maliciously crafted requests
You are affected if your installed YouTrack version is lower than 2018.4.49852 and your admin interface is accessible to authenticated users without CSRF token validation.
