Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
XML External Entity (XXE): The processing of XML external entities was not properly restricted within several SQL operators, allowing remote attackers to potentially read local files or trigger denial of service conditions.
Improper Certificate Validation: The HttpUtils#getURLConnection method disabled hostname verification for HTTPS connections, exposing the application to man-in-the-middle (MITM) attacks when connecting to external services.
Information Exposure: Sensitive HTTP request data, including URL parameters and payload data containing credentials, was previously logged to the system logs in debug mode.
