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 Fix(es):
A flaw in libsoup’s HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing. Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.(CVE-2025-14523)
A flaw was found in libsoup's NTLM (NT LAN Manager) authentication module. When NTLM authentication is enabled, a local attacker can exploit a stack-based buffer overflow vulnerability in the md4sum() function. This allows the attacker to overwrite adjacent memory, which may result in arbitrary code execution with the privileges of the affected application.(CVE-2026-0719)
