Credential disclosure via cross-host redirect forwarding
Published Apr 24, 2025 · Updated Jul 25, 2026
Authorization-header exposure in GNOME libsoup before 3.6.5 allows remote attackers to obtain credentials through an HTTP redirect. Redirect handling forwards the original request's Authorization header when the Location target changes to a different host. A victim application must send credentials and follow the redirect; the receiving host can replay those credentials against the original host.
