CVE-2026-17350 is a medium-severity flaw (CVSS 5.4) affecting pgadmin 4. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
The per-tool permission system (custom roles / role-based tool permissions, introduced in pgAdmin 4 9.3) did not enforce its permission check consistently. In SERVER mode, pgAdmin 4 gates each tool behind a per-tool Flask-Security permission, but the permission decorator (permissions_required) was applied only to a single "front door" route per tool. Every other backend route and Socket.IO handler in that tool's workflow relied solely on pga_logi

pgadmin pgadmin 4 UPGRADE
Affected: >= 9.3 and < 9.17
Fixed in: 9.17
Safe to downgrade to: a release before 9.3
1. Check installed version
apt-cache policy pgadmin-4 || rpm -q pgadmin-4 || pgadmin-4 --version
2. UPGRADE to 9.17 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade pgadmin-4
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade pgadmin-4
Note
Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.
3. If no update is available yet, DOWNGRADE to a release before 9.3 (Debian / Ubuntu)
apt-cache madison pgadmin-4
sudo apt install pgadmin-4=<VERSION_BEFORE_9.3>
sudo apt-mark hold pgadmin-4
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list pgadmin-4
sudo dnf downgrade pgadmin-4-<VERSION_BEFORE_9.3>
sudo dnf versionlock add pgadmin-4
Downgrade risk
Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.
After downgrade
Restart the service, and keep the package held until a fixed release ships.
