Information disclosure via sensitive URL query strings
Published Aug 28, 2026 · Updated Aug 28, 2026
Sensitive data exposure in Le-yan Medical Practice Management System 2.4.2.8 through 2.5.1.9 allows attackers to obtain information from browser history or logs. The application places sensitive values in HTTP GET query strings, which browsers retain in history and infrastructure can record in logs. No authentication is required to cause the exposure, while disclosure depends on access to the victim's retained history or recorded request logs.
