CVE-2021-25986: Cross-site Scripting in django-wiki

December 2, 2021 (updated November 19, 2024)

In Django-wiki, versions 0.0.20 to 0.7.8 are vulnerable to Stored Cross-Site Scripting (XSS) in Notifications Section. An attacker who has access to edit pages can inject JavaScript payload in the title field. When a victim gets a notification regarding the changes made in the application, the payload in the notification panel renders and loads external JavaScript.
