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, 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.(CVE-2026-1801)

    A flaw was found in libsoup's WebSocket frame processing when handling incoming messages. If a non-default     configuration is used where the maximum incoming payload size is unset, the library may read memory     outside the intended bounds. This can cause unintended memory exposure or a crash. Applications using     libsoup's WebSocket support with this configuration may be impacted.(CVE-2026-0716)

    A flaw was identified in libsoup, a widely used HTTP library in GNOME-based systems. When processing     specially crafted HTTP Range headers, the library may improperly validate requested byte ranges. In     certain build configurations, this could allow a remote attacker to access portions of server memory     beyond the intended response. Exploitation requires a vulnerable configuration and access to a server     using the embedded SoupServer component.(CVE-2026-2443)

    A flaw was found in libsoup. An integer underflow vulnerability occurs when processing content with a     zero-length resource, leading to a buffer overread. This can allow an attacker to potentially access     sensitive information or cause an application level denial of service.(CVE-2026-2369)
