id: CVE-2022-0424

info:
  name: Popup by Supsystic < 1.10.9 - Subscriber Email Addresses Disclosure
  author: s4e-io
  severity: medium
  description: |
    The Popup by Supsystic WordPress plugin before 1.10.9 does not have any authentication and authorisation in an AJAX action, allowing unauthenticated attackers to call it and get the email addresses of subscribed users
  impact: |
    Unauthenticated attackers can obtain email addresses of all subscribed users via an unprotected AJAX endpoint, potentially facilitating phishing campaigns or spam attacks.
  remediation: Fixed in 1.10.9
