CVE-2026-53540

Python-Multipart is a streaming multipart parser for Python. Prior to 0.0.31, parseform did not validate the Content-Length header before using it to bound its chunked read of the request body. A negative Content-Length turned the bounded read into a read-until-EOF, so the entire body was loaded...

CVE-2026-49432 Apache ActiveMQ, Apache ActiveMQ All, Apache ActiveMQ Stomp: STOMP negative content-length enables denial of service

Improper Input Validation vulnerability in Apache ActiveMQ, Apache ActiveMQ All, Apache ActiveMQ Stomp.
