| summary: CSRF token reuse vulnerability in github.com/gofiber/fiber/v2 |
| description: |- |
| A cross-site request forgery vulnerability in this package can allow an attacker |
| to inject arbitrary values and forge malicious requests on behalf of a user. The |
| attacker may inject arbitrary values without any authentication, or perform |
| various malicious actions on behalf of an authenticated user, potentially |
| compromising the security and integrity of the application. |
| |
| The vulnerability is caused by improper validation and enforcement of CSRF |
| tokens within the application. For 'safe' methods, the token is extracted from |
| the cookie and saved to storage without further validation or sanitization. In |
| addition, the CSRF token is validated against tokens in storage but not |
| associated with a session, nor by using a Double Submit Cookie Method, allowing |
| for token reuse. |

| notes: |
| - There is a closely related vulnerability (GO-2023-2116), and it is not clear which fix applies to which vulnerability, so I have marked both fixes as applying to both vulnerabilities. |
