CVE-2023-50839Network attack vector

Unauthenticated database disclosure via unprepared ticket query

Published Dec 28, 2023 · Updated Apr 28, 2026

SQL injection in JoomSky JS Help Desk 2.8.1 and earlier allows remote attackers to read database data through crafted ticket inputs. The ticket lookup path inserts the email and trackingid parameters into an existing SQL query without sufficient escaping or parameter preparation. No authentication or user interaction is required; injected clauses can extract sensitive database records, while the CNA reports no integrity impact.
