PrestaShop - Information Disclosure

id: CVE-2025-51586

info:
  name: PrestaShop - Information Disclosure
  author: mastercho
  severity: medium
  description: |
    User enumeration vulnerability in the AdminLogin controller in PrestaShop 1.7 through 8.2.2 allows remote attackers to obtain administrators user email addresses via manipulation of the id_employee and reset_token parameters. An attacker who has access to the Back Office login URL can trigger the password reset form to disclose the associated email address in a hidden field, even when the provided reset token is invalid. This issue has been fixed in 8.2.3.
  impact: |
    Attackers can gain sensitive information via the reset password feature, potentially leading to further attacks.
  remediation: |
    Update to version 8.2.1 or later.
