CVE-2025-8808Public exploitNetwork attack vector

Code execution via unsanitized spreadsheet export

Published Aug 10, 2025 · Updated Aug 12, 2025

CSV injection in xujeff Tianti 2.0 through 2.3 allows remote authenticated users to plant formulas in exported user data. The exportOrder method copies unsanitized username, real-name, mobile, and role values into a spreadsheet, so leading formula characters remain executable. Low-privileged account access is required, and code runs only after an administrator exports the user list, opens it in a spreadsheet application, and activates the malicious cell.
