CVE-2026-53540 not yet assigned priority: Debian including 1 source packages (python-multipart), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): open 5.
Python-Multipart is a streaming multipart parser for Python. Prior to 0.0.31, parse_form() 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 into memory in a single read instead of in fixed-size chunks. This vulnerability is fixed in 0.0.31.
