Cross-project article disclosure via draft creation
Published Aug 17, 2026 · Updated Aug 17, 2026
Improper access control in JetBrains YouTrack before 2026.1.13903 and 2026.2.17950 lets remote authenticated users read restricted articles. JetBrains states that the draft creation endpoint exposed restricted articles from other projects, and product documentation shows that article-draft creation surfaces already published similar articles while a summary is being typed, indicating that this lookup did not enforce project and article visibility restrictions. Exploitation requires a valid account that can work with article drafts, and the published record bounds the impact to confidentiality because it describes article reading only, not modification or deletion.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
