Auth bypass in Labredescefetrj Wegia

CVE-2026-76633

WeGIA before 3.9.2 contains an authorization bypass vulnerability in the password change flow that allows any authenticated user to change their account password without providing existing credentials by exploiting the unconditional exclusion of the alterarSenha method from permission checks in controle/control.php.
