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.
-
Check YouTrack versionLog into YouTrack as administrator and navigate to Administration > System > Overview, or access the /api/debug/info endpoint to retrieve the exact version numberAffected if The installed version is lower than 2024.3.52635 (e.g., 2024.2.x, 2024.1.x, etc.)
-
Identify Ruby syntax feature usageReview your YouTrack projects for any issues, articles, or markdown content that contain Ruby code blocks (using ```ruby fences) or Ruby syntax highlighting in code mirrorsAffected if Ruby code blocks or syntax highlighting features are actively used in any project
-
Verify Ruby syntax detector is enabledCheck Administration > System > Features or look for language-specific syntax detection settings in YouTrack's configuration to confirm if Ruby syntax highlighting is enabledAffected if Ruby syntax detection is enabled in YouTrack settings
Your YouTrack instance is affected if it runs a version lower than 2024.3.52635 and you have Ruby syntax highlighting or code detection enabled for any content.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
