Name of the Vulnerable Software and Affected Versions Fiber versions prior to 2.50.0

Description A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the application, which allows an attacker to obtain tokens and forge malicious requests on behalf of a user. This can lead to unauthorized actions being taken on the user's behalf, potentially compromising the security and integrity of the application. The vulnerability is caused by improper validation and enforcement of CSRF tokens within the application, specifically due to the lack of token association with the original requestor.

Recommendations For versions prior to 2.50.0, upgrade to version 2.50.0 or later to address the vulnerability. As a temporary workaround, consider implementing proper CSRF protection mechanisms, such as the Double Submit Cookie method or the Synchronizer Token Pattern using sessions. Additionally, users should take extra security measures like captchas or Two-Factor Authentication (2FA) and set Session cookies with SameSite=Lax or SameSite=Secure, and the Secure and HttpOnly attributes.
