CVE-2026-17348 is a medium-severity flaw (CVSS 6.5) affecting pgadmin 4. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
In SERVER mode, pgAdmin 4 enforces authentication per route via the @pga_login_required decorator; the application's before_request hook only handles desktop-mode auto-login and the Kerberos/Webserver-auth redirect, so any route shipped without the decorator is reachable without authentication (CWE-306). This is the same defect class previously fixed as CVE-2026-12046 (the sqleditor close/update_connection routes). A follow-up sweep, prompted by

After downgrade
Restart the service, and keep the package held until a fixed release ships.
