Description
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.
This issue affects pgAdmin 4: before 9.19.

VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
The records we use list no fixed release for CVE-2026-116249. Check the upstream advisory for a patched version, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
