Analysis Summary
# Vulnerability: Authorization Bypass in MCPHub
## CVE Details
- **CVE ID**: CVE-2025-13822
- **CVSS Score**: Not explicitly provided in the article (Estimated High base score due to bypass nature)
- **CWE**: CWE-639 (Authorization Bypass Through User-Controlled Key)
## Affected Systems
- **Products**: MCPHub
- **Versions**: All versions prior to 0.11.0
- **Configurations**: Default installations where endpoints are exposed to the network.
## Vulnerability Description
MCPHub suffers from an authorization bypass vulnerability because several API endpoints lack the necessary authentication middleware. This architectural flaw allows an unauthenticated actor to interact with these endpoints directly. By manipulating user-controlled keys or identifiers, an attacker can perform actions on behalf of other registered users, effectively inheriting their privileges and performing unauthorized operations within the system.
## Exploitation
- **Status**: Disclosed via Coordinated Vulnerability Disclosure (CVD); no mention of active exploitation in the wild.
- **Complexity**: Low (Exploitation involves accessing unprotected endpoints).
- **Attack Vector**: Network (Remote)
## Impact
- **Confidentiality**: High (Ability to perform actions/view data as other users)
- **Integrate**: High (Ability to modify or delete data as other users)
- **Availability**: Medium to High (Depending on the actions available via the unprotected endpoints)
## Remediation
### Patches
- **Version 0.11.0**: This version contains the necessary fixes to enforce authentication across all sensitive endpoints. Users are urged to upgrade immediately.
### Workarounds
- No specific workarounds were provided in the advisory; however, restricting network access to the MCPHub dashboard or API to trusted IP addresses can reduce the attack surface until patching is complete.
## Detection
- **Indicators of Compromise**: Review web server logs for requests to administrative or user-specific endpoints originating from unauthenticated sessions.
- **Detection Methods**: Security teams can use automated scanners to identify endpoints that return data or perform actions without requiring a valid session token or cookie.
