CVE-2021-28070Public exploitNetwork attack vector

Account deletion via forged multidelete request

Published Aug 25, 2021 · Updated Aug 3, 2024

Cross-site request forgery in PopojiCMS 2.0.1 allows remote attackers to delete user accounts through the user multidelete route. The route accepts attacker-chosen account identifiers in a cross-origin POST and processes the deletion under the active session without verifying request intent. An administrator must remain signed in and open the attacker's page, after which the selected account is deleted.
