HTTP::Tiny versions before 0.095 for Perl forward credential headers to cross-origin redirect targets. When the server returns a 3xx redirect, `_maybe_redirect` follows the `Location:` header and `_prepare_headers_and_cb` re-merges the caller's `headers` argument into the new request, without checking whether the redirect target shares an origin with the original URL. Caller-supplied `Authorization`, `Cookie` and `Proxy-Authorization` headers are therefore re-sent to whatever host the redirect names, across scheme, host or port boundaries, and including `https` to `http` downgrades that expose them in plaintext on the wire. The HTTP::Tiny POD note that "Authorization headers will not be included in a redirected request" applied only to the URL-userinfo Basic-auth path, not to headers passed explicitly by the caller.

The remote openSUSE 16 host has a package installed that is affected by a vulnerability as referenced in the openSUSE- SU-2026:21529-1 advisory.

    Changes in perl-HTTP-Tiny:

    - updated to 0.096
    - CVE-2026-7017: Fixed forwarded credential headers to cross-origin redirect targets (bsc#1271020)
    - Caller-supplied Authorization, Cookie, and Proxy-Authorization       headers are now stripped on cross-origin redirects by default. Use       allow_credentialed_redirects to opt out.
    - Redirects are no longer automatically followed when going from https to http.
      Use allow_downgrade to revert to the original behaviour.

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

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

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2026:0610 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2026-7017:
    HTTP::Tiny versions before 0.095 for Perl forward credential headers to cross-origin redirect targets.
    When the server returns a 3xx redirect, _maybe_redirect follows the Location: header and
    _prepare_headers_and_cb re-merges the caller's headers argument into the new request, without checking     whether the redirect target shares an origin with the original URL. Caller-supplied Authorization, Cookie     and Proxy-Authorization headers are therefore re-sent to whatever host the redirect names, across scheme,     host or port boundaries, and including https to http downgrades that expose them in plaintext on the wire.

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