CVE-2026-2963Public exploitNetwork attack vector

Database disclosure via unsanitized id and offsnum

Published Feb 23, 2026 · Updated Feb 23, 2026

SQL injection in Jinher OA C6 20260210 allows remote authenticated users to read database data through crafted id or offsnum parameters. The OfficeSupplyTypeRight.aspx endpoint fails to sanitize these user-controlled values before database processing, enabling time-based blind inference through WAITFOR delays. A valid ASP.NET session is required, and the demonstrated proof of concept extracts the current database name through response timing rather than returning query results directly.
