Short explanation

A privilege escalation vulnerability exists in phpMyFAQ from version 4.2.0-alpha.2 before 4.2.0-beta via the group permission API. The update endpoints check held rights without regard to language or category scope and write unrestricted group grants.

Why does it matter?

This vulnerability allows administrators with narrow-scope rights to include themselves in expanded groups, granting them unrestricted FAQ creation, editing, and publishing access across all languages and categories.

What should be done?

  • Follow vendor advisories and updates
  • Upgrade phpMyFAQ to version 4.2.0-beta or an unaffected release
  • Audit group permissions and scope limits for administrator accounts

Show the technical text from the sources

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. Non-superadmin administrators holding GROUP_EDIT can grant a group a right they hold only in a narrow scope and self-join it via updateMembers, gaining unrestricted FAQ create, edit, and publish access across all languages and categories.
