Securing Flask Applications

These cyber-attacks are mainly due to broken access control problems, Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), Server-Side Request Forgery (SSRF), SQL Injection, and Denial-of-Service (DoS), as well as outdated modules and libraries.

Using third-party libraries can inflict risks to the Flask applications because some library codes can contain coding errors or vulnerabilities. This is especially true for codes sourced from outdated third-party modules and libraries with unreliable sources.
It is easier to build Flask components and features with external modules, such...
