Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Django REST framework versions before 3.17.2 are affected. When AdminRenderer renders a 400 Bad Request for an invalid write request, it can invoke the view's GET handler even if GET is denied by the permission class, and include the protected GET data in the HTML response. An attacker needs a view that allows POST or another write method but denies GET, and the client must request the HTML renderer. Upgrade to djangorestframework 3.17.2.
