5.3 mediumEPSS 0.5%

Medium (5.3) in haxx curl. EPSS 0.5% chance of exploitation in the next 30 days.

Successfully using libcurl to do a transfer over a specific HTTP proxy (`proxyA`) with **Digest** authentication and then changing the proxy host to a second one (`proxyB`) for a second transfer, reusing the same handle, makes libcurl wrongly pass on the `Proxy-Authorization:` header field meant for `proxyA`, to `proxyB`.
