The first thing to watch out for is SQL injections. To reduce the risk, use parameterized queries rather than string concatenation and validate the data you inject. Cross-site scripting (XSS) is another common threat. To combat it, it is recommended to use Content Security Policy (CSP) and carefully filter input data. Cross-site request forgery (CSRF) also requires attention. To protect against it, use tokens and check referer headers. Also, beware of insufficient authentication and authorization, and ensure proper session management.
