A command injection vulnerability exists in the andreahaku codex_mcp tool affecting an unknown function in src/codex-process-simple.ts. The vulnerability arises from improper handling of the argument 'model' and requires local access to exploit. The product does not use versioning, so affected versions cannot be precisely identified. The issue was reported early to the project, but no response or patch has been provided yet.
AI Analysis
Technical Summary
The vulnerability in andreahaku codex_mcp up to commit 1ff521cc6cc57cfe56ddef946c644b8534771390 involves command injection via manipulation of the 'model' argument in an unknown function within src/codex-process-simple.ts. Exploitation requires local access and low privileges, with no user interaction needed. The product lacks versioning, preventing clear identification of affected versions. The project was notified but has not issued a fix or response. The CVSS 3.1 base score is 5.3, reflecting low severity with impacts on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation could allow an attacker with local access and low privileges to execute arbitrary commands on the affected system, potentially leading to limited confidentiality, integrity, and availability impacts. However, the attack surface is constrained by the requirement for local access and the absence of user interaction.
Mitigation Recommendations
No official fix or patch is currently available as the project has not responded to the issue report. Users should monitor the project for updates or advisories. Until a fix is provided, restricting local access to trusted users and environments is recommended to reduce risk.
