Authenticated data disclosure via unchecked simulated GET
Published Aug 11, 2026 · Updated Aug 11, 2026
Information disclosure in Django REST framework before 3.17.2 allows remote authenticated users to read GET-protected data. AdminRenderer.render() simulates GET while handling an invalid write request and calls view.get() without view.check_permissions(), placing the protected GET representation in the 400 HTML response. Exploitation requires AdminRenderer, HTML content negotiation, an allowed write method, a denied GET, and a validation error; JSON responses are unaffected.
