BIT-PYTHON-2026-15310 zipfile: bzip2/LZMA/Zstandard members decompress without a max_length bound, defeating chunked-read memory limits

When decompressing crafted zip files using the bzip/LZMA/Zstandard compressions, Python could use an attacker-controlled size to pre-allocate memory, possibly resulting in memory exhaustion...

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...

python-multipart: Negative Content-Length in parse_form buffers the entire body in memory

Summary 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 into memory in a single read instead of in fixed-size chunks. Details...

OESA-2026-2615 libsoup security update

libsoup is an HTTP client/server library for GNOME. It uses GObjects and the glib main loop, to integrate well with GNOME applications, and also has a synchronous API, for use in threaded applications. Security Fixes: A flaw was found in libsoup. A remote attacker could exploit an unsigned to...

The vulnerability of the soup_body_input_stream_read_chunked() function in the LibSoup library allows a attacker to circumvent existing security restrictions, implement a cache poisoning attack, or gain unauthorized access to protected information.

The vulnerability of the soupbodyinputstreamreadchunked function in the LibSoup library is related to deficiencies in HTTP request processing. Exploiting this vulnerability allows a malicious actor to circumvent existing security measures, execute a cache poisoning attack, or gain unauthorized...

UBUNTU-CVE-2026-6324

A flaw was found in libsoup. A remote attacker could exploit an unsigned to signed conversion error in the soupbodyinputstreamreadchunked function by sending a malicious HTTP request. This vulnerability occurs when libsoup operates behind a non-libsoup proxy server or as a proxy in front of a...

CVE-2026-39803 HTTP/1 chunked body reader ignores length cap in bandit

Allocation of Resources Without Limits or Throttling vulnerability in mtrudel bandit allows unauthenticated remote denial of service via memory exhaustion. The chunked clause of 'Elixir.Bandit.HTTP1.Socket':readdata/2 in lib/bandit/http1/socket.ex ignores the caller-supplied :length option when...
