curl: curl: Information disclosure due to secure cookie attribute bypass

A flaw was found in curl. When a Set-Cookie: header uses a tab character instead of a space before the Secure attribute, curl incorrectly stores the cookie without the Secure flag. This can lead to information disclosure, as the cookie may then be sent over unencrypted HTTP connections to the sam...

curl: libcurl: Information disclosure via improper Public Suffix List boundary check

A flaw was found in libcurl when libpsl support is enabled. A remote attacker could exploit this vulnerability by setting a Set-Cookie header with a Domain attribute that explicitly matches a public suffix. This improper handling causes libcurl to save the cookie with a wildcard domain scope,...

CURL-CVE-2026-80255 secure cookie attribute bypass with tab

A Set-Cookie: header using tab horizontal tab, ASCII code 9 instead of space ascii code 32 immediately before the Secure attribute causes curl to store the cookie without its Secure flag. The cookie might then wrongfully be sent over plaintext HTTP on subsequent requests to the same host...
