Vulnerability from fkie_nvd - Published: 2026-03-30 18:16 - Updated: 2026-06-17 10:29
Severity
8.2 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N
Summary
A cross-session information disclosure vulnerability exists in the awesome-llm-apps project in commit e46690f99c3f08be80a9877fab52acacf7ab8251 (2026-01-19). The affected Streamlit-based GitHub MCP Agent stores user-supplied API tokens in process-wide environment variables using os.environ without proper session isolation. Because Streamlit serves multiple concurrent users from a single Python process, credentials provided by one user remain accessible to subsequent unauthenticated users. An attacker can exploit this issue to retrieve sensitive information such as GitHub Personal Access Tokens or LLM API keys, potentially leading to unauthorized access to private resources and financial abuse.

El agente GitHub MCP basado en Streamlit afectado almacena tokens de API proporcionados por el usuario en variables de entorno a nivel de proceso usando os.environ sin un aislamiento de sesi\u00f3n adecuado. Debido a que Streamlit sirve a m\u00faltiples usuarios concurrentes desde un \u00fanico proceso de Python, las credenciales proporcionadas por un usuario permanecen accesibles para usuarios no autenticados posteriores. Un atacante puede explotar este problema para recuperar informaci\u00f3n sensible como Tokens de Acceso Personal de GitHub o claves de API de LLM, lo que podr\u00eda llevar a un acceso no autorizado a recursos privados y abuso financiero."
