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 HTTP client library. This vulnerability, known as CRLF (Carriage Return     Line Feed) Injection, occurs when an HTTP proxy is configured and the library improperly handles URL-     decoded input used to create the Host header. A remote attacker can exploit this by providing a specially     crafted URL containing CRLF sequences, allowing them to inject additional HTTP headers or complete HTTP     request bodies. This can lead to unintended or unauthorized HTTP requests being forwarded by the proxy,     potentially impacting downstream services. (CVE-2026-1467)

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

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8020-1 advisory.

    It was discovered that libsoup did not correctly handle certain URL-decoded input, which could allow for     HTTP header injection. A remote attacker could possibly use this issue to cause a denial of service or     execute arbitrary code. (CVE-2026-1467, CVE-2026-1536)

    It was discovered that libsoup did not correctly handle removal of the Proxy-Authorization header. A     remote attacker could possibly use this issue to leak sensitive information. (CVE-2026-1539)
