PrestaShop psgdpr versions through 1.4.3 fail to validate that GDPR consent log entries are attributed to the authenticated customer. Authenticated attackers can submit arbitrary customer identifiers to create forged consent records for other customers, corrupting audit logs.
AnalysisAI
Authenticated customers on PrestaShop stores that have the psgdpr GDPR-compliance module installed at version 1.4.3 or earlier can forge GDPR consent audit records belonging to other customers by supplying attacker-chosen customer identifiers to the module's front-office consent AJAX endpoint (FrontAjaxGdpr.php), corrupting the integrity of consent logs. Only a valid customer account is required - no administrator privileges, no user interaction, and no special store configuration beyond an active module - and publicly available exploit code exists. …
