CVE-2026-116252— pgAdmin 4: Materialized view refresh redirects its connection through a crafted database name

Quick assessment

Affected
pgadmin.org pgAdmin 4
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

pgAdmin 4 在刷新物化视图时，将目标数据库名称原封不动地传递给 psql 的 --dbname 参数。libpq 会将包含 "=" 字符（或 postgresql:// URI）的 --dbname 值视为完整的连接字符串，其中的关键字会覆盖 pgAdmin 原本提供的 host（主机）、port（端口）等其他设置。因此，任何拥有 CREATEDB 权限的角色都可以创建一个名称符合上述特征的数据库，从而将 pgAdmin 为执行刷新而启动的 psql 进程重定向到由创建者指定的任意主机和端口，并将连接用户保

Vulnerability Title
pgAdmin 4: Materialized view refresh redirects its connection through a crafted database name
Source: CVE Program / CVE List V5
Vulnerability Description
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.
