Upgrade gitea.dev/modules/uri to version 1.27.0 or higher.
Overview
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) through the uri.Open and migration asset download paths in modules/uri/uri.go and services/migrations/dump.go. An attacker can make the server fetch internal services, cloud metadata, or local files by supplying a crafted asset download URL or file:// URI during repository migration. The vulnerable code uses raw http.Get() without the host-matching protections applied elsewhere in Gitea, so migration processing can be driven to contact attacker-chosen endpoints and read attacker-specified file paths. This can expose internal network resources, instance metadata, and sensitive configuration data to anyone able to trigger the affected migration flows.
