CVE-2024-50580
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 multiple XSS were possible due to insecure markdown parsing and custom rendering rule
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 confidenceMultiple Cross-Site Scripting (XSS) vulnerabilities existed in YouTrack's markdown processing and custom rendering rules. Attackers could inject malicious scripts through specially crafted markdown content that would execute in the browsers of users viewing the content.

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 installationAccess the YouTrack administration area (usually at /admin/system) or check the installation directory for version informationAffected if YouTrack is found running in the environment
-
Determine installed YouTrack versionNavigate to Administration > System > Overview in the YouTrack web interface, or check the build number in the installation logsAffected if The version displayed is below 2024.3.47707
-
Verify markdown feature is in useCheck if issue descriptions, comments, or custom fields contain markdown-formatted content by viewing any YouTrack projectAffected if Markdown rendering is enabled and users create content with markdown syntax (this is enabled by default)
-
Check for custom rendering rulesNavigate to Administration > System > Markdown in YouTrack settings and review if any custom rendering rules are configuredAffected if Custom rendering rules are defined in the YouTrack markdown configuration
The environment is affected if the installed YouTrack version is less than 2024.3.47707 and markdown content rendering is available to users (which is enabled by default).
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.
