CVE-2025-48432Network attack vector

Log forgery via unescaped request paths

Published Jun 5, 2025 · Updated Jun 11, 2025

Log injection in Django 4.2 before 4.2.23, 5.1 before 5.1.11, and 5.2 before 5.2.3 allows remote attackers to forge logs via URLs. Internal HTTP response logging passes request.path control characters to log formatters without safe encoding, including newlines and ANSI escape sequences. An unauthenticated request must reach a logged response path; the result is limited to altered log appearance or structure in terminals and downstream systems, not Django's security model.
