CVE-2026-82879Network attack vectorHinoki check available

Authenticated share access bypass via unbound tickets

Published Aug 31, 2026 · Updated Aug 31, 2026

Incorrect authorization in DataEase before 2.10.26 allows remote authenticated users to bypass share controls and alter tickets. ShareTicketManage accepts a ticket without matching its UUID to the requested share, while related endpoints issue LinkTokens without required tickets and update, delete, or enumerate records without ownership checks. A valid session is required; cross-share access also requires a valid ticket and target password, while ticket tampering requires knowledge of another ticket.
