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.","severity":{"version":"3.1","score":5.3,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.00421,"percentile":0.36728,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":true,"fix_available":true},"cwes":["CWE-444"],"published":"2026-02-03T20:12:21Z","modified":"2026-11-05T05:40:51Z","exploits":[{"source":"pocgithub","id":"misterdengi/CVE-2026-1801C","title":"misterdengi/CVE-2026-1801C","date":"2026-08-29","url":"https://github.com/misterdengi/CVE-2026-1801C"}],"fixes":[{"ecosystem":"Azure

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.\r\n\r\nSecurity Fix(es):\n\nA flaw was found in SoupServer. This HTTP request smuggling vulnerability occurs because SoupServer improperly handles requests that combine Transfer-Encoding: chunked and Connection: keep-alive headers. A remote, unauthenticated client can exploit this by sending specially crafted requests, causing SoupServer to fail to close the connection as required by RFC 9112. This allows the attacker to smuggle additional requests over the persistent connection, leading to unintended request processing and potential denial-of-service (DoS) conditions.(CVE-2026-1760)\n\nA flaw was found in libsoup, an HTTP client/server library.

The HTTP/2 server in libsoup may not fully validate the values of pseudo-headers :scheme, :authority, and :path, which may allow a user to cause a denial of service (DoS).(CVE-2025-32908)\n\nA flaw was identified in the NTLM authentication handling of the libsoup HTTP library, used by GNOME and other applications for network communication.
