Title
pgAdmin 4: libpq uses the pgAdmin service account's own password file and client certificate
Summary
When a server in pgAdmin 4 had no password file, client certificate or client key configured, or the configured one could not be found, pgAdmin left the parameter out of the connection and libpq fell back to the defaults of the operating-system account running pgAdmin: ~/.pgpass, ~/.postgresql/postgresql.crt and postgresql.key, or PGPASSFILE, PGSSLCERT and PGSSLKEY. In server mode any user could therefore connect to a server with the service account's saved passwords or client certificate, and supplying only a copy of its public certificate was enough for libpq to pair it with the service account's private key. A pg_service.conf entry, or a maintenance database name read as a connection string by pg_dumpall, could bring the same files back for the utilities. The fix gives each of these parameters a value in server mode, the user's own file or otherwise a path that can never be opened, in the connection string, in the environment of the utilities and in the --dbname connection string that ranks above a service entry. Desktop mode is unchanged. This issue affects pgAdmin 4: before 9.19.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
