CVE-2026-1801— Libsoup: libsoup: http request smuggling via malformed chunk headers

Libsoup: libsoup: http request smuggling via malformed chunk headers

A flaw was found in libsoup, an HTTP client/server library. This HTTP Request Smuggling vulnerability arises from non-RFC-compliant parsing in the soup_filter_input_stream_read_line() logic, where libsoup accepts malformed chunk headers, such as lone line feed (LF) characters instead of the required carriage return and line feed (CRLF). A remote attacker can exploit this without authentication or user interaction by sending specially crafted chunked requests. This allows libsoup to parse and process multiple HTTP requests from a single network message, potentially leading to information disclosure.

HTTP请求的解释不一致性(HTTP请求私运)

libsoup 环境问题漏洞

libsoup是GNOME项目的一款GNOME的HTTP客户端/服务器库。 libsoup存在环境问题漏洞，该漏洞源于soup_filter_input_stream_read_line逻辑中非RFC兼容的解析接受格式错误的块标头，可能导致HTTP请求夹带攻击和信息泄露。
