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

  - Guzzle is an extensible PHP HTTP client. Prior to 7.15.2 and 8.0.1, Guzzle gives a transport the request     URI as text and supplies the Host header separately. The cURL handlers set CURLOPT_URL to the URI exactly     as written and push that Host into CURLOPT_HTTPHEADER; StreamHandler does the same through fopen().
    libcurl then parses the authority itself, percent-decoding it and, on an IDN-capable build, applying IDNA     mapping, and uses the result to resolve, connect, name the TLS peer and address a proxy CONNECT, while the     supplied Host suppresses the aligned one libcurl would have generated. For a URI host written as     127.0.0.%31, filter_var() rejects the host as an IP literal, yet libcurl decodes it to 127.0.0.1 and     reaches loopback with no DNS lookup while the server receives Host: 127.0.0.%31. An attacker who     influences a fetched URI can therefore reach a host the application's checks excluded and read whatever     the host exposes of the response. The same divergence moves Guzzle's own decisions onto a spelling the     transport does not use: no_proxy selects proxy routing from the literal host, and RedirectMiddleware     decides from it whether to strip Authorization and Cookie. Exploitation requires the application to build     a request URI from untrusted input and to make a host decision before handing it to Guzzle. This issue is     fixed in versions 7.15.2 and 8.0.1. (CVE-2026-69246)

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