CVE-2022-39284

Summary

CodeIgniter is a PHP full-stack web framework. In versions prior to 4.2.7 setting $secure or $httponly value to true in Config\Cookie is not reflected in set_cookie() or Response::setCookie(). As a result cookie values are erroneously exposed to scripts. It should be noted that this vulnerability does not affect session cookies. Users are advised to upgrade to v4.2.7 or later. Users unable to upgrade are advised to manually construct their cookies either by setting the options in code or by constructing Cookie objects. Examples of each workaround are available in the linked GHSA.
