Technical details
The vulnerability exists in pgAdmin 4's server API create and update endpoints, which failed to validate whether the requesting user was an administrator before processing a "shared" flag that makes a server visible to all users. Additionally, the servers.json import removed non-administrator shared entries only after validation, allowing a file with an invalid entry to bypass this check. An attacker with user registration capability could share a server with all users, directing them to an attacker-controlled host to intercept database credentials.
