CVE-2023-45141Network attack vector

Request forgery via reusable unbound CSRF tokens

Published Oct 16, 2023 · Updated Sep 16, 2024

CSRF in GoFiber Fiber before 2.50.0 allows remote attackers to forge requests on behalf of users through reusable tokens. The middleware/csrf implementation validates tokens in storage without binding them to the requester that generated them. Exposure requires an application to use middleware/csrf, and forged actions remain bounded by the affected user's session privileges.
