Browser script execution via unencoded subscriber email
Published Jun 4, 2020 · Updated Aug 4, 2024
Stored XSS in phpList before 3.5.4 allows remote authenticated users to execute script in an administrator's browser via a crafted subscriber email. The user-edit handler accepts the email field without input validation, stores it, and the subscriber-search view copies that value into JavaScript without output encoding. A logged-in user who can edit a subscriber record can plant the payload, and script execution requires an administrator to open the affected search content.
