CVE-2026-16074Public exploitNetwork attack vector

Authenticated internal-service access via unchecked plugin URLs

Published Jul 17, 2026 · Updated Jul 17, 2026

Server-side request forgery in AstrBot 4.25.0 through 4.25.2 allows remote authenticated users to access internal services. The update_plugin and update_all_plugins handlers pass attacker-controlled download_url, download_urls, and proxy values into outbound requests without validating the destination. A Dashboard JWT is required; successful requests can reach loopback, private-network, or metadata endpoints from the AstrBot server and expose returned data.
