The Ignition component before 1.16.15, and 2.0.x before 2.0.6, for Laravel has a "fix variable names" feature that can lead to incorrect access control.
The Ignition component before 2.0.5 for Laravel mishandles globals, get, post, cookie, and env. NOTE: in the 1.x series, versions 1.16.15 and later are unaffected as a consequence of the CVE-2021-43996 fix.
