PYSEC-2026-1851 Denial of service (DoS) via deformation `multipart/form-data` boundary

Summary 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...
