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 confidenceIn JetBrains YouTrack versions prior to 2024.2.34646, the Guest User Account feature incorrectly permitted guest users to attach files to articles. This represents an authorization/privilege escalation issue where low-privilege guest users could perform file attachment actions that should have been restricted.

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 installed YouTrack versionLog in to YouTrack as an administrator and navigate to Administration > System > Updates or check the version displayed in the YouTrack footer. Alternatively, access the /api/debug/info endpoint if available to retrieve version information.Affected if The installed version is lower than 2024.2.34646 (e.g., 2024.1, 2023.x, etc.)
