It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1460 advisory.

    A flaw was found in libsoup. An attacker who can control the input for the Content-Disposition header can     inject CRLF (Carriage Return Line Feed) sequences into the header value. These sequences are then     interpreted verbatim when the HTTP request or response is constructed, allowing arbitrary HTTP headers to     be injected. This vulnerability can lead to HTTP header injection or HTTP response splitting without     requiring authentication or user interaction. (CVE-2026-1536)

    A flaw was found in the libsoup HTTP library that can cause proxy authentication credentials to be sent to     unintended destinations. When handling HTTP redirects, libsoup removes the Authorization header but does     not remove the Proxy-Authorization header if the request is redirected to a different host. As a result,     sensitive proxy credentials may be leaked to third-party servers. Applications using libsoup for HTTP     communication may unintentionally expose proxy authentication data. (CVE-2026-1539)

    libsoup: heap buffer overflow in soup_content_sniffer_sniff (CVE-2026-2369)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.
