A flaw was found in libsoup. A remote attacker could exploit an unsigned to signed conversion error in the `soup_body_input_stream_read_chunked()` function by sending a malicious HTTP request. This vulnerability occurs when libsoup operates behind a non-libsoup proxy server or as a proxy in front of a non-libsoup backend server. Successful exploitation can allow an attacker to bypass security controls, poison web caches, or gain unauthorized access.

According to the versions of the libsoup packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    A flaw was found in libsoup. When establishing HTTPS tunnels through a configured HTTP proxy, sensitive     session cookies are transmitted in cleartext within the initial HTTP CONNECT request. A network-positioned     attacker or a malicious HTTP proxy can intercept these cookies, leading to potential session hijacking or     user impersonation.(CVE-2026-5119)

    A flaw was found in libsoup. A remote attacker could exploit an unsigned to signed conversion error in the     `soup_body_input_stream_read_chunked()` function by sending a malicious HTTP request. This vulnerability     occurs when libsoup operates behind a non-libsoup proxy server or as a proxy in front of a non-libsoup     backend server. Successful exploitation can allow an attacker to bypass security controls, poison web     caches, or gain unauthorized access.(CVE-2026-6324)

    A 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)

Tenable has extracted the preceding description block directly from the EulerOS libsoup security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
