GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

FKIE_CVE-2026-4199

Vulnerability from fkie_nvd - Published: 2026-03-16 14:20 - Updated: 2026-06-17 10:56
Severity
5.3 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
Summary
A vulnerability was identified in bazinga012 mcp_code_executor up to 0.3.0. Affected by this issue is the function installDependencies of the file src/index.ts. Such manipulation leads to command injection. The attack can only be performed from a local environment. The exploit is publicly available and might be used. It is best practice to apply a patch to resolve this issue. The project was informed of the problem early through an issue report but has not responded yet.
