- LWP::UserAgent now strips Authorization and Proxy-Authorization headers on cross-origin redirects (a different scheme, host, or port) to prevent credential leakage to the redirect target. Same-origin redirects retain credentials. Opt out with allow_credentialed_redirects => 1. CVE-2026-8368 reported by Kai Zen; PoC and initial patch by Stig Palmquist. - LWP::UserAgent now refuses https to http redirects by default to prevent leaking remaining request headers and bodies over plaintext. Opt in with allow_downgrade => 1. Related hardening alongside CVE-2026-8368; PoC by Stig Palmquist.
