Vulnerability Title
Joro: Unauthenticated Cross-Origin Plugin Upload Leads to RCE
Source: CVE Program / CVE List V5
Vulnerability Description
Joro is a web exploitation framework. Prior to version 1.1.1, Joro's default proxy mode exposes a local API on 127.0.0.1:9090 that performs no authentication and applies a wildcard CORS policy. Because plugin uploads use the CORS-safelisted multipart/form-data content type, cross-origin JavaScript on any page the operator visits can reach privileged endpoints - including uploading a native plugin and triggering a restart - directly through the operator's browser, with no preflight or credentials. Since plugins execute on load, this yields unauthenticated remote code execution as the operator's user from a single page visit. This issue has been patched in version 1.1.1.
