Apache2 - Transfer-Encoding Chunked XSS

Apache2 PHP before 5.6.38, 7.0.x before 7.0.32, 7.1.x before 7.1.22, and 7.2.x before 7.2.10 contain a reflected cross-site scripting vulnerability caused by mishandling of chunked transfer-encoding requests in sapi/apache2handler/sapiapache2.c. Attackers can execute malicious scripts via crafted...

CVE-2026-56810

CVE-2026-56810 affects mint: a memory-denial vulnerability in Mint.HTTP1.decode_body/5 where chunked HTTP response bodies are buffered in an unbounded data_buffer until the entire declared chunk length completes. The chunk size is parsed with no upper bound, enabling a remote attacker to send an ...

CVE-2026-11946

An unauthenticated remote attacker can exhaust server memory via the GetEndpoints Discovery Service in open62541. The endpointUrl field of GetEndpointsRequest is not validated for length. An attacker can declare an arbitrarily large string up to 4.09 GB via the UInt32 length field delivered acros...

io.netty/netty-codec-http: Netty: Request smuggling via incorrect parsing of HTTP/1.1 chunked transfer encoding extension values

A flaw was found in Netty. A remote attacker could exploit this vulnerability by sending specially crafted HTTP/1.1 chunked transfer encoding extension values. Due to incorrect parsing of quoted strings, this flaw enables request smuggling attacks, potentially allowing an attacker to bypass...

netty-codec-http: Netty is vulnerable to request smuggling due to incorrect parsing of chunk extensions

A flaw in Netty’s HTTP/1.1 chunked encoding parser allows newline LF characters in chunk extensions to be incorrectly treated as the end of the chunk-size line instead of requiring the proper CRLF sequence. This discrepancy can be exploited in rare cases where a reverse proxy interprets the same...

PYSEC-2026-348 h11 accepts some malformed Chunked-Encoding bodies

Impact A leniency in h11's parsing of line terminators in chunked-coding message bodies can lead to request smuggling vulnerabilities under certain conditions. Details HTTP/1.1 Chunked-Encoding bodies are formatted as a sequence of "chunks", each of which consists of: - chunk length - \r\n - leng...

EUVD-2026-37789

Tinyproxy through 1.11.3, fixed in commit ff45d3b, fails to reconcile conflicting Content-Length and Transfer-Encoding: chunked headers, forwarding both verbatim to the backend while using Content-Length to determine how many request body bytes to consume. Remote attackers can desynchronize the...

GHSA-V9PG-7XVM-68HF 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...
