Hi,

The following vulnerability was published for cpp-httplib.

CVE-2026-102944[0]:
| cpp-httplib is a C++ header-only HTTP/HTTPS library. Prior to
| 0.51.0, create_redirect_client() removes Host, Proxy-Authorization,
| and Authorization headers when following a cross-origin 301, 302,
| 307, or 308 redirect but leaves Cookie headers attached.
| detail::redirect() copies the request for those redirect codes, so
| cookies supplied directly or through default_headers_ are sent to
| the redirect target. An attacker who controls a redirect response,
| or a network position for a non-HTTPS origin, can receive session
| cookies intended for the original origin. A 303 redirect is not
| affected because that path clears all request headers. This issue is
| fixed in version 0.51.0.


If you fix the vulnerability please also make sure to include the
