"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1012 advisory.

    The various Is methods (IsPrivate, IsLoopback, etc) did not work as expected for IPv4-mapped IPv6
    addresses, returning false for addresses which would return true in their traditional IPv4 forms.
    (CVE-2024-24790)

    The net/http package accepted data in the chunked transfer encoding containing an invalid chunk-size line
    terminated by a bare LF. When used in conjunction with a server or proxy which incorrectly interprets a
    bare LF in a chunk extension as part of the extension, this could permit request smuggling.
    (CVE-2025-22871)

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
