CVE-2026-7814: Pgadmin 4 cross-site scripting vulnerability

Pgadmin · Pgadmin 4

Stored cross-site scripting (XSS) vulnerability in pgAdmin 4 Browser Tree and Explain Visualizer modules. User-controlled PostgreSQL object names (database, schema, table, column, etc.) were assigned to DOM elements via innerHTML, allowing crafted object names containing HTML markup to execute attacker-supplied JavaScript in the browser of any pgAdmin user who navigated to or executed EXPLAIN over the malicious object. Fix replaces innerHTML with textContent. This issue affects pgAdmin 4: before 9.15.
