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.

CVE-2026-53649 affects Joro, a web exploitation framework by BishopFox, in versions prior to 1.1.1. The vulnerability stems from Joro's default proxy mode exposing a local API on 127.0.0.1:9090 with no authentication and a wildcard CORS policy. Because plugin uploads leverage the CORS-safelisted multipart/form-data content type, any cross-origin JavaScript from a page visited by the operator can reach privileged API endpoints without preflight checks or credentials. An attacker can abuse this to upload a malicious native plugin and trigger a restart, achieving unauthenticated remote code execution as the operator's user. The attack requires only a single page visit by the operator, making it highly accessible. The issue has been fully patched in Joro version 1.1.1. Users are strongly advised to upgrade immediately.
