CVE-2024-0609Network attack vector

Unauthenticated stored XSS via unescaped api_key output

Published Mar 29, 2024 · Updated Apr 8, 2026

Stored XSS in WP ERP 1.13.1 and earlier allows remote attackers to inject scripts through the unauthenticated api_key parameter. The bundled Google API client example index.php accepts the parameter without sufficient sanitization and outputs it without escaping. No account is required; the stored payload executes when a user later opens the injected page, enabling browser-context data access or modification.
