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.

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 version numberLog into YouTrack as an administrator, navigate to Administration > System > Overview, and locate the 'YouTrack version' field. Alternatively, check the build number in the installation directory or startup logs.Affected if The installed version is less than 2024.3.47707 (for example, 2024.2.12345 or any version in the 2024.1.x, 2023.x, or earlier series).
-
Confirm markdown feature is in useVerify that markdown formatting is enabled for issues, comments, or descriptions. Navigate to Administration > System > Markdown settings or review any issue that uses markdown syntax (such as **bold**, *italic*, [links](url), or code blocks).Affected if Markdown rendering is enabled, which is the default state in YouTrack.
