Summary

A member with the permission `EDIT_PERMISSIONS` and access to the "Security" section is able to re-assign themselves (or another member) to `ADMIN` level.

CMS Fields for the member are constructed using DirectGroups instead of Groups relation which results in bypassing security logic preventing privilege escalation.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
