Summary

phpMyFAQ from 4.2.0-alpha.2 before 4.2.0-beta Privilege Escalation via Group Permissions API

Details

phpMyFAQ from 4.2.0-alpha.2 before 4.2.0-beta contains a privilege escalation vulnerability in the group permission API, whose updatePermissions and updateMembers endpoints check held rights without regard to language or category scope and write unrestricted group grants.
