CVE-2023-0721Network attack vector

Code execution via unneutralized exported CSV formulas

Published Jun 9, 2023 · Updated Apr 8, 2026

CSV injection in Roxnor MetForm 3.3.0 and earlier allows remote attackers to place executable formulas in exported form-entry data. The entry export path writes attacker-controlled form values into CSV cells without neutralizing formula-triggering prefixes. Execution requires an administrator to export the entries and open the resulting file in spreadsheet software configured to evaluate the formula.
