## Technical details

CSV formula injection vulnerability in the Tenders module export functionality where user-controlled data (event names, templates) is not sanitized before inclusion in CSV files. An authenticated attacker with low privileges can input values beginning with formula characters (e.g., =, +, @) that are interpreted by spreadsheet applications and executed via DDE or similar mechanisms when a victim opens the file. Successful exploitation requires user interaction (file download and opening) and results in command execution, information disclosure, or system resource interaction under the victim's context.
