Web applications are often the entry point to an organization's internal network and sensitive data. They typically have high access to back-end systems, such as databases and file servers, and can interact with many users and systems. Therefore, it is becoming a valuable target for attackers.

Web application security vulnerabilities are weaknesses or flaws in the security of web applications that attackers can exploit to obtain unauthorized access, steal confidential information, or cause other types of damage.

Here are some top trending web application security vulnerabilities:

1. SQL injection (SQLi): SQLi vulnerability occurs when an attacker injects malicious SQL code into a web application's database. It can allow attackers to view, modify, or delete data from the application's database.
2. Security misconfiguration: This vulnerability occurs when an application's security settings are improperly configured. It can allow attackers to exploit weaknesses in the application's security mechanisms.
3. Cross-Site Scripting (XSS): XSS vulnerability occurs when an attacker injects malicious code into web pages viewed by other users. It can allow attackers to steal user sensitive information or hijack user sessions.
4. Cross-Site Request Forgery (CSRF): CSRF vulnerability occurs when an attacker executes unauthorized actions on behalf of a victim user. It can allow attackers to make a fraudulent transaction or change user account settings.
5. Server-Side Request Forgery (SSRF): SSRF vulnerability occurs when an attacker sends HTTP requests from the vulnerable server to other servers or services on the internet, often bypassing firewalls and other security measures. It can allow attackers to read or modify data on those servers or even execute arbitrary code on them.
6. Broken access control: This vulnerability occurs when an application fails to enforce access control policies properly. It can allow attackers to obtain unauthorized access to data or functionality.
7. Insufficient logging and monitoring: This vulnerability occurs when an application fails to log and monitor user activity properly. It can make it challenging to detect and respond to security incidents on the application.
8. Insecure cryptographic storage: This vulnerability occurs when sensitive data is not adequately encrypted, leaving it open to theft or unauthorized access.
9. Broken authentication and session management: These vulnerabilities occur when a web application does not authenticate or manage user sessions properly. It can allow attackers to impersonate users, steal session tokens, or bypass access controls.
10. Vulnerable and outdated components: These vulnerabilities are caused by using outdated or vulnerable third-party components such as libraries, frameworks, and other software packages. It can allow attackers to exploit vulnerabilities and gain unauthorized access to a web application, steal sensitive data, or compromise the entire system.
