What happened

In server mode pgAdmin 4 resolves a server's password file, SSL certificate, key, CRL and SSH tunnel identity file relative to the user's storage directory, but get_complete_file_path() only stripped leading slashes before joining the two. A path such as "../<another user>/.pgpass", set through the server dialog, the REST API or a servers.

json import, therefore named another user's file, and connecting used that user's saved passwords, client certificate or SSH key. The sslkeylogfile connection parameter was passed to libpq unchanged, so a path outside storage let libpq create or append a file as the account running pgAdmin.

make_conninfo() also quoted connection parameter values but not their names, so a crafted parameter name could smuggle additional keyword=value pairs past these checks.

The fix requires the resolved path, with symbolic links followed, to stay inside the user's storage directory or the named shared storage directory, confines sslkeylogfile the same way, and accepts only exact libpq keywords as connection parameter names. A refused path or keyword is reported instead of letting libpq fall back to a default.

About this data

This record was ingested from a data source. Retrieved: Oct 30, 2026, 21:20 UTC. Ingestion is not an independent editorial investigation.

NVD status: Received. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
