Name of the Vulnerable Software and Affected Versions Django versions 6.0 through 6.0.4 Django versions 5.2 through 5.2.13

Description ASGI requests with a missing or understated Content-Length header can bypass the FILE UPLOAD MAX MEMORY SIZE limit. This allows large files to be loaded into memory, which can lead to service degradation and a potential denial-of-service. ASGI (Asynchronous Server Gateway Interface) is a standard for asynchronous Python web servers to communicate with web applications.

Recommendations Update versions 6.0 through 6.0.4 to version 6.0.5. Update versions 5.2 through 5.2.13 to version 5.2.14. Configure a limit at the web server level to avoid relying solely on FILE UPLOAD MAX MEMORY SIZE.
