Description
The strapi/strapi (Core Admin / Webhook Runner) package is vulnerable to a semi-blind SSRF via a webhook follow-redirect. The webhook dispatcher automatically follows HTTP redirects without performing post-redirect IP resolution or RFC1918/link-local boundary checks. Non-2xx responses from target endpoints are captured and reflected directly back to the caller.
