NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Alpine. See How to fix? for Alpine:3.22 relevant fixed versions and status.

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.
