The OWASP Top Ten is a list of the most critical web application security risks. The current version (2021) of the OWASP Top Ten includes the following vulnerabilities:

1. Injection: Injection flaws, such as SQL, NoSQL, OS, and LDAP injection, occur when untrusted data is sent to an interpreter as part of a command or query. The attacker's malicious input can trick the interpreter into executing unintended commands or accessing unauthorized data.

2. Broken Authentication and Session Management: Broken authentication and session management flaws can enable attackers to gain access to user accounts, impersonate users, or elevate privileges without proper authentication.

3. Cross-Site Scripting (XSS): XSS flaws occur when web applications fail to properly sanitize user input. An attacker can use this vulnerability to inject malicious scripts into a web page viewed by other users.

4. Security Misconfiguration: Security misconfiguration vulnerabilities can arise when default configurations, unnecessary features, or weak passwords are used. These vulnerabilities can allow attackers to gain unauthorized access to sensitive data or execute malicious code.

5. Insecure Cryptographic Storage: Insecure cryptographic storage vulnerabilities occur when sensitive data, such as passwords or credit card numbers, is not properly encrypted or hashed. This can allow attackers to easily access and steal the sensitive data.

6. Insufficient Logging and Monitoring: Insufficient logging and monitoring can make it difficult for organizations to detect and respond to security incidents. This can result in attackers gaining persistent access to systems and data.

7. Insecure Communication: Insecure communication vulnerabilities can arise when sensitive data is transmitted over insecure channels, such as HTTP instead of HTTPS. Attackers can intercept and manipulate this data to gain unauthorized access to systems and data.

8. Broken Access Control: Broken access control vulnerabilities occur when attackers can access resources or functionality that should be restricted. This can allow attackers to gain unauthorized access to sensitive data or execute unauthorized actions.

9. Insufficient Attack Protection: Insufficient attack protection vulnerabilities occur when applications do not adequately protect against common attacks, such as cross-site scripting or SQL injection. Attackers can exploit these vulnerabilities to gain access to systems and data.

10. Using Components with Known Vulnerabilities: Using components with known vulnerabilities can introduce security risks into an application. Attackers can exploit these vulnerabilities to gain unauthorized access to systems and data or execute unauthorized actions.
