CVE-2026-14846Network attack vector

Personal-data exposure via Alias formula injection

Published Jul 13, 2026 · Updated Jul 13, 2026

CSV formula injection in PrestaShop 8.2.1 allows remote authenticated users to embed formulas in GDPR data exports. The address-update function inadequately validates the Alias parameter, and the CSV export writes that value so a spreadsheet executes it as a formula. Exploitation requires authenticated address modification and a victim opening the export, exposing personal data to formula-driven access.
