CVE-2026-92386
Published:October 20, 2026
Updated:November 02, 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.
