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 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)

    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 libsoup's WebSocket implementation when using the permessage-deflate extension. The     extension's decompression loop (inflate()) processes data in chunks without enforcing an upper boundary     limit on the output buffer size. While libsoup limits the incoming compressed frame size via     max_incoming_payload_size, it fails to track or limit memory allocation during decompression. A separate     check for decompressed size (max_total_message_size) exists but executes only after inflation is complete,     and it is entirely disabled by default for client connections. A remote, unauthenticated attacker can     exploit this by sending a small, highly compressed payload (a decompression bomb), causing unbounded     memory allocation that triggers an Out-of-Memory (OOM) crash and a Denial of Service     (DoS).(CVE-2026-15709)
