What you should know about PHP security vulnerabilities

This report is a practical guide on PHP security that explains common vulnerabilities (SQL injection, code injection, XSS, CSRF, file inclusion, session/cookie issues), the business impact of breaches, and mitigation strategies such as input sanitization, prepared statements, keeping PHP and dependencies updated, and using scanners like Snyk to detect interpreter and dependency vulnerabilities; it is advisory and educational rather than an incident report.
