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.
