PrestaShop Checkout 1.3.0-4.4.0 and 5.0.0-5.0.4 - Account Takeover via Express Checkout Email Validation Bypass
PrestaShop Checkout is the PrestaShop official payment module in partnership with PayPal. Starting in version 1.3.0 and prior to versions 4.4.1 and 5.0.5, missing validation on the Express Checkout feature allows silent login, enabling account takeover via email. The vulnerability is fixed in versions 4.4.1 and 5.0.5. No known workarounds exist.
