        Hey, i found that any user can can access all user's PII info and vaccine info, through unauthenticated endpoint /vaccination-manager/api/vax-proof-list.php.


After directory fuzzing on /vaccination-manager/ a file stands out, api.php.


Let's visit that url  https://2c19d123df3d-newrouge.a.firstbloodhackers.com/vaccination-manager/api.php . we see this page.



We see  that /vaccination-manager/api/vax-proof-list.php  will return each record of vaccination.
