Worked on enhancing security scanning in the joernio/joern repository by developing a new PHP frontend vulnerability detection feature within queryDB. This feature expanded automated coverage to identify critical issues such as SQL injection, command injection, code injection, unrestricted file uploads, and XSS in PHP code. The approach involved writing new Joern queries and implementing comprehensive unit tests to ensure reliability of the security checks. Additionally, improved the PHP version check logic to reduce false negatives and improve maintainability. Leveraged skills in Joern, PHP, Scala, and static security analysis to strengthen early detection of insecure patterns in PHP frontend code.
