Hi,

The following vulnerability was published for libwww-perl.

CVE-2026-8368[0]:
| LWP::UserAgent versions before 6.83 for Perl leak Authorization and
| Proxy-Authorization headers on cross-origin redirects.  On a 3xx
| response, the redirect handler strips only Host and Cookie before
| issuing the follow-up request. Caller-supplied Authorization and
| Proxy-Authorization headers are sent unchanged to the redirect
| target, including across scheme, host, or port changes.  A redirect
| to an attacker controlled host therefore discloses the caller's
| credentials to that host.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
