python-engineio has possible denial of service due to maximum payload size sometimes not being enforced

ImpactThere are two specific configurations of the python-engineio server in which the size of incoming messages is not checked before the messages are loaded into memory. An attacker can take advantage of these to cause unnecessary memory allocations in the python-engineio server. The two cases...

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...
