CVE-2026-53649: CWE-306: Missing Authentication for Critical Function in BishopFox joro
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.

Technical Analysis
CVE-2026-53649 describes a missing authentication vulnerability in BishopFox's Joro web exploitation framework before version 1.1.1. The default proxy mode exposed a local API on 127.0.0.1:9090 without authentication and applied 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 without preflight or credentials. This enables uploading a native plugin and triggering a restart, resulting in unauthenticated remote code execution as the operator's user. The issue is fixed in version 1.1.1.
Potential Impact
An attacker can execute arbitrary code remotely as the operator's user by exploiting the unauthenticated local API and permissive CORS policy. This includes uploading and executing native plugins, which can compromise the operator's environment with high confidentiality, integrity, and availability impact.
Mitigation Recommendations
Upgrade Joro to version 1.1.1 or later, where this vulnerability has been patched. No other mitigation is indicated or required as the fix is official and addresses the authentication and CORS issues.
