Technical details
The feishu-auth and dingtalk-auth authentication plugins in Apache APISIX are vulnerable to session fixation attacks via CSRF. An unauthenticated attacker can craft a link that, when clicked by an authenticated user, causes their browser session on protected routes to be fixed to the attacker's identity. This requires user interaction (clicking the link) and network access, but no prior authentication. The attacker gains the ability to hijack user sessions and perform unauthorized actions in the victim's name.
