Authenticated arbitrary entity deletion via mailbox endpoint
Published Aug 17, 2026 · Updated Aug 17, 2026
Missing authorization in JetBrains YouTrack before 2025.3.156085, 2026.1.13914, and 2026.2.18095 allows remote authenticated users to delete arbitrary entities. JetBrains has disclosed only that the mailbox endpoint omits an authorization check on delete operations; no public advisory, CVE record, or patch identifies the specific handler or entity type exposed. Exploitation requires a valid low-privilege account and network reachability to the application, and the published CVSS vector indicates integrity and availability impact from unauthorized deletions rather than direct data disclosure.

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.
