CVE-2026-53649 Details
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.
A critical vulnerability allowing unauthenticated cross-origin plugin uploads has been identified in Joro versions through 1.1.0. In the default proxy mode, a local API is exposed on 127.0.0.1:9090 without authentication and with a permissive CORS policy. This allows cross-origin JavaScript to upload plugins directly through the operator's browser, bypassing preflight checks and credentials. Exploiting this vulnerability could lead to remote code execution as the operator's user, triggered by the uploaded plugin's initialization.
Users can update to Joro version 1.1.1 or later, where this vulnerability has been patched.
