CVE-2022-38702Network attack vector

Spreadsheet formula execution via unsanitized CSV exports

Published Nov 7, 2023 · Updated Apr 28, 2026

CSV injection in WP CSV Exporter 2.0 and earlier allows remote authenticated users to place executable formulas in exported files. The public advisory identifies improper neutralization of formula elements during CSV generation but does not disclose the affected field, export function, or escaping failure. Exploitation requires a privileged user to export attacker-controlled WordPress content and open the file in a formula-capable spreadsheet, where the formula can modify data.
