CVE-2026-58521Public exploitNetwork attack vector

SQL injection via unsafe year range filter

Published Jul 1, 2026 · Updated Jul 1, 2026

SQL injection in Wikimedia Foundation MediaWiki Cargo before 1.43.9, 1.44.6, and 1.45.4 allows remote attackers to alter database queries. The year-range filter incorporates attacker-controlled range text into an SQL command without neutralizing SQL metacharacters before execution. No authentication or user interaction is required; injected queries can expose or alter Cargo data and interrupt database-backed service.
