Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Versions of phpMyFAQ (phpmyfaq/phpmyfaq and thorsten/phpmyfaq) before 4.1.5 are affected, and 4.1.5 fixes the issue. In the group permissions endpoint, an administrator who holds only the GROUP_EDIT right can grant a group rights they do not themselves hold. Because members of that group inherit those rights, the administrator can escalate privileges, potentially up to full administrative control. Upgrade to 4.1.5.
