Cookie Attribute Injection

undici is vulnerable to cookie attribute injection. The vulnerability is due to insufficient sanitization of cookie domain and unparsed values in setCookie, allowing attacker-controlled input to inject or override cookie attributes such as SameSite, Secure, and HttpOnly, potentially weakening...

SUSE CVE-2026-16729

undici's setCookie function does not fully sanitize cookie attributes. In undici before 6.28.0, from 7.0.0 up to before 7.29.0, and from 8.0.0 up to before 8.9.0, a domain value is not checked for semicolons and entries in the unparsed array are not sanitized, so attacker-influenced input can...

undici vulnerable to cookie attribute injection via unsanitized domain and unparsed setCookie fields

Impact The setCookie function has two attribute injection paths. validateCookieDomain does not reject semicolons validateCookiePath already does at 0x3B, so a domain value like example.com; SameSite=None lands verbatim as Domain=example.com; SameSite=None. The unparsed array's loop only checks ea...

undici: Undici: Cookie attribute injection allows bypassing security protections

A flaw was found in undici, where its setCookie function does not fully sanitize cookie attributes. A remote attacker could exploit this by providing specially crafted input to the domain or unparsed fields, leading to the injection of additional cookie attributes. This vulnerability can allow an...
