CVE-2026-21721 · Dashboard Permissions Scope Bypass Enables Cross‑Dashboard Privilege Escalation

This page contains facts from public vulnerability sources. Check the original advisory before updating.

The dashboard permissions API does not verify the target dashboard scope and only checks the dashboards.permissions:* action. As a result, a user who has permission management rights on one dashboard can read and modify permissions on other dashboards. This is an organization‑internal privilege escalation.
