Session Middleware Token Injection Vulnerability

A security vulnerability has been identified in the Fiber session middleware where a user can supply their own session_id value, leading to the creation of a session with that key.

Impact

The identified vulnerability is a session middleware issue in GoFiber versions 2 and above. This vulnerability allows users to supply their own session_id value, resulting in the creation of a session with that key. If a website relies on the mere presence of a session for security purposes, this can lead to significant security risks, including unauthorized access and session fixation attacks. All users utilizing GoFiber's session middleware in the affected versions are impacted.

Patches

The issue has been addressed in the latest patch. Users are strongly encouraged to upgrade to version 2.52.5 or higher to mitigate this vulnerability.

Workarounds

Users who are unable to upgrade immediately can apply the following workarounds to reduce the risk:

  1. Validate Session IDs: Implement additional validation to ensure session IDs are not supplied by the user and are securely generated by the server.
  2. Session Management: Regularly rotate session IDs and enforce strict session expiration policies.
