During a source code review, we commonly identify various types of vulnerabilities, including SQL injection, cross-site scripting (XSS), buffer overflows, and insecure API calls. We also look for issues related to improper error handling, authentication flaws, and hardcoded credentials. Additionally, our reviews assess adherence to coding standards, ensuring best practices are followed to enhance overall code quality. By identifying and addressing these vulnerabilities, we help organizations fortify their applications against potential attacks and ensure compliance with industry regulations, safeguarding sensitive data and maintaining user trust.
