The version of golang installed on the remote host is prior to 1.25.8-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3203 advisory.

    url.Parse insufficiently validated the host/authority component and accepted some invalid URLs.
    (CVE-2026-25679)

    On Unix platforms, when listing the contents of a directory using File.ReadDir or File.Readdir the     returned FileInfo could reference a file outside of the Root in which the File was opened. The impact of     this escape is limited to reading metadata provided by lstat from arbitrary locations on the filesystem     without permitting reading or writing files outside the root. (CVE-2026-27139)

    Actions which insert URLs into the content attribute of HTML meta tags are not escaped. This can allow XSS     if the meta tag also has an http-equiv attribute with the value refresh. A new GODEBUG setting has been     added, htmlmetacontenturlescape, which can be used to disable escaping URLs in actions in the meta content     attribute which follow url= by setting htmlmetacontenturlescape=0. (CVE-2026-27142)

Tenable has extracted the preceding description block directly from the SUSE 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.

  - url.Parse insufficiently validated the host/authority component and accepted some invalid URLs.
    (CVE-2026-25679)

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

The version of Golang running on the remote host is prior to 1.25.8, or 1.26.x prior to 1.26.1. It is, therefore, affected by multiple vulnerabilities as referenced in the advisory.

  - The Go standard library function net/url.Parse insufficiently validated the host/authority component and     accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The     function should have rejected this as invalid. To prevent this behavior, net/url.Parse now rejects IPv6     literals that do not appear at the start of the host subcomponent of a URL. (CVE-2026-25679)

  - A TOCTOU (time-of-check/time-of-use) race condition exists in os.Root on Unix platforms. The     File.ReadDir and File.Readdir methods populate os.FileInfo using lstat, which can escape the root     boundary through a symlink race condition. An attacker can exploit this by replacing a directory     with a symlink pointing outside the root between listing directory contents and calling     DirEntry.Info(), allowing retrieval of file metadata (size, modification time, permissions) for     files outside the root. This does not permit reading or writing files outside the root.
    (CVE-2026-27139)

  - Actions which insert URLs into the content attribute of HTML meta tags are not escaped. This can allow     XSS if the meta tag also has an http-equiv attribute with the value 'refresh'. A new GODEBUG setting has     been added, htmlmetacontenturlescape, which can be used to disable escaping URLs in actions in the meta     content attribute which follow 'url=' by setting htmlmetacontenturlescape=0. (CVE-2026-27142)
