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.

According to the versions of the perl-HTTP-Tiny package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

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.

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.
