CVE-2026-92386
Published:October 14, 2026
Updated:October 15, 2026
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 encountering the too long line, ignoring all subsequent valid cookies in the file.
