Detailsinfo

A vulnerability was found in pgadmin.org pgAdmin up to 9.18. It has been rated as problematic. Affected by this issue is the function database_conninfo of the component Materialized View Refresh. The manipulation of the argument dbname with an unknown input leads to a redirect vulnerability. Using CWE to declare the problem leads to CWE-601. A web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a Redirect. This simplifies phishing attacks. Impacted is integrity. CVE summarizes:

pgAdmin 4's materialized view refresh passed the target database's name to psql's --dbname argument unchanged. libpq treats a --dbname value containing "=" (or a postgresql:// URI) as a full connection string, whose keywords override the host, port and other settings pgAdmin had supplied. A database whose name is such a string, which any role with CREATEDB can create, therefore redirected the psql process pgAdmin starts for the refresh to a host and port of the creator's choosing, and the connecting user's saved server password was presented to that endpoint. It also let the pgAdmin host be made to open connections to arbitrary addresses. The same weakness was fixed for Backup, Restore, Maintenance and Import/Export Data in earlier releases (CVE-2026-86862); the materialized view refresh was the remaining caller. The fix routes the name through the same database_conninfo() helper, so libpq treats it strictly as a database name. This issue affects pgAdmin 4: before 9.19.
