CURL-CVE-2026-11856
cross-origin Digest auth state leak
Successfully using libcurl to do a transfer to a specific HTTP origin
(hostA) with Digest authentication and then changing the origin to a
different one (hostB) for a second transfer, reusing the same handle, makes
libcurl wrongly pass on the Authorization: header field meant for hostA,
to hostB.
