CVE-2026-4190Public exploitNetwork attack vector

SQL injection via unneutralized sort argument

Published Mar 15, 2026 · Updated Mar 15, 2026

SQL injection in JawherKl node-api-postgres 2.0 through 2.5 allows remote attackers to alter PostgreSQL queries through the sort argument. User.getAll in models/user.js incorporates the sort value into an SQL statement without neutralizing SQL syntax. No privileges or user interaction are required; successful injection permits database reads, writes, or service interruption within the application's PostgreSQL account permissions.
