CVE-2022-47442Network attack vector

Spreadsheet code execution via unsanitized CSV export

Published Nov 7, 2023 · Updated Apr 28, 2026

CSV injection in AyeCode Ltd UsersWP 1.2.3.9 and earlier allows remote authenticated users to place formulas in exported user data. The process_users_export function writes attacker-controlled profile fields to CSV cells without neutralizing formula-leading characters. Subscriber-level access supplies the crafted data, but code execution on an administrator's computer requires the exported file to be opened in a vulnerable spreadsheet configuration.
