CURL-CVE-2026-86412 server-set cookie erases cookie jar

A remote HTTP server can set a cookie that curl accepts and writes to a Netscape cookie jar but cannot reload. On the next invocation using the same path for --cookie and --cookie-jar, curl fails before connecting, then the cleanup procedure replaces the jar with an empty file, deleting cookies f...

CURL-CVE-2026-86414 leaking host credentials to HTTP proxy

An HTTP proxy can trick libcurl into sending the origin's credentials Basic password, or a Negotiate/Kerberos ticket to the proxy itself, by answering the CONNECT tunnel request with 401 WWW-Authenticate: instead of the expected 407 Proxy-Authenticate:...

HSTS cache import drops longer-lived child

Importing a includeSubDomains parent HSTS entry before a longer-lived child entry, silently drops the child. Consequently, when the parent expires, the child's valid HSTS policy is lost, causing curl to issue unencrypted HTTP requests rather than upgrading to HTTPS...

server-set cookie aborts cookie jar load

When writing a long cookie name and value to a Netscape cookie jar, a remote HTTP server can make curl write a record that exceeds its line-length parsing limit. Consequently, any subsequent curl invocation reading from that same cookie jar using --cookie silently aborts parsing prematurely upon...
