CVE ID : CVE-2024-53981

Published : Dec. 2, 2024, 4:15 p.m. | 1 hour ago

Description : python-multipart is a streaming multipart parser for Python. When parsing form data, python-multipart skips line breaks (CR r or LF n) in front of the first boundary and any tailing bytes after the last boundary. This happens one byte at a time and emits a log event each time, which may cause excessive logging for certain inputs. An attacker could abuse this by sending a malicious request with lots of data before the first or after the last boundary, causing high CPU load and stalling the processing thread for a significant amount of time. In case of ASGI application, this could stall the event loop and prevent other requests from being processed, resulting in a denial of service (DoS). This vulnerability is fixed in 0.0.18.

Severity: 7.5 | HIGH
