CVE-2026-47693Public exploitNetwork attack vector

Spreadsheet formula execution via unsanitized CSV fields

Published Jun 23, 2026 · Updated Jun 23, 2026

CSV injection in Poweradmin before 4.2.4 and 4.3.0 through 4.3.2 allows remote authenticated users to plant formulas in exported logs. Four log export controllers pass actor and account usernames directly to fputcsv() without neutralizing leading formula characters. Exploitation requires user-creation rights, followed by an administrator exporting an affected log and opening the CSV in a spreadsheet; formulas can present phishing links or exfiltrate adjacent log data.
