Source Advisory Statement

### Impact An unauthenticated attacker with access to the back-office URL can manipulate the id_employee and reset_token parameters to enumerate valid back-office employee email addresses. Impacted parties: Store administrators and employees: their email addresses are exposed. Merchants: risk of phishing, social engineering, and brute-force attacks targeting admin accounts. ### Patches PrestaShop 8.2.3 ### Workarounds You must upgrade, or at least apply the changes from the PrestaShop 8.2.3 patch.
