Kerentanan Authentication Bypass by Capture-replay pada haxx curl. Skor CVSS 3.1 9.1 (Critical) menurut CISA ADP.

Deskripsi (NVD)

When reusing a libcurl handle for sequential transfers driven by environment-variable proxy configuration, libcurl fails to clear the proxy authentication state between requests. Specifically, if the initial transfer authenticates against `proxyA` using Digest auth, a subsequent transfer routed through `proxyB` erroneously leaks the `Proxy-Authorization:` header intended solely for `proxyA`.
