Summary
The Strapi content management system's Core Admin webhook feature is affected. Attackers who can configure webhooks can use it to make the server send requests to internal or otherwise restricted network addresses by following redirects, and the server returns error responses from those targets back to the attacker, exposing some information about internal services.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original 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.
