CVE-2023-45128Public exploitNetwork attack vector

Forged requests via unbound reusable CSRF tokens

Published Oct 16, 2023 · Updated Sep 16, 2024

CSRF in GoFiber Fiber before 2.50.0 allows remote attackers to forge state-changing requests through its CSRF middleware. For safe methods, the middleware stores a cookie-supplied token without validation and accepts stored tokens without binding them to a session. Exposure requires an application to use the affected middleware; forged requests can perform actions available to the targeted session.
