CVE-2026-19203

A flaw was found in Jetty. A remote attacker can exploit this vulnerability by sending specially crafted HTTP/1.1 chunked requests. This can cause Jetty and an intermediary proxy to interpret different request boundaries, potentially leading to HTTP request smuggling. This issue arises from Jetty...

Astra Linux – Vulnerability in Puma

Puma is a web server for Ruby/Rack applications built for parallelism. Prior to version 6.4.2, Puma exhibited incorrect behavior when parsing chunked transfer encoding bodies, allowing HTTP request smuggling. The fixed versions limit the size of chunk extensions. Without this limitation, an...

Name of the Vulnerable Software and Affected Versions facil.io versions 0.7.5 through 0.7.6 Description A denial-of-service issue exists in the HTTP/1.1 chunked transfer encoding parser. An unauthenticated remote attacker can crash the server by sending a single POST request with a...

CVE-2026-66338 Libsoup: libsoup: http request smuggling via permissive chunk-size parsing in soup_body_input_stream_read_chunked()

A flaw was found in libsoup. The chunked transfer encoding parser uses a permissive parsing function for chunk sizes that silently accepts inputs violating RFC 9112, including leading whitespace, plus sign prefixes, and trailing invalid characters. When libsoup operates behind a strict frontend...

AZL-76736 CVE-2026-1801 affecting package libsoup 3.0.4-12

A flaw was found in libsoup, an HTTP client/server library. This HTTP Request Smuggling vulnerability arises from non-RFC-compliant parsing in the soupfilterinputstreamreadline logic, where libsoup accepts malformed chunk headers, such as lone line feed LF characters instead of the required...

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...
