CVE-2023-24580Network attack vector

Service interruption via unbounded multipart file parts

Published Feb 15, 2023 · Updated Mar 18, 2025

Resource exhaustion in Django 3.2 before 3.2.18, 4.0 before 4.0.10, and 4.1 before 4.1.7 allows remote attackers to interrupt service. The Multipart Request Parser accepts an unbounded number of file parts, consuming memory and file descriptors without an early file-count limit. No authentication or user interaction is required, but a deployed application must expose a multipart file-upload endpoint to the network.
