CVE-2026-29872

Estado: AnalizadaAlta (8.2)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Red sin autenticación (AV:N/PR:N/UI:N) permite acceso remoto a la aplicación expuesta. Vulnerabilidad de divulgación de información: credenciales (tokens, claves API) y datos de sesión anteriores quedan en variables de entorno accesibles. CWE-522 (almacenamiento inseguro de credenciales) y CWE-200 (

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

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 sesión adecuado. Debido a que Streamlit sirve a múltiples usuarios concurrentes desde un único proceso de Python, las credenciales proporcionadas por un usuario permanecen accesibles para usuarios no autenticados posteriores. Un atacante puede explotar este problema para recuperar información sensible como Tokens de Acceso Personal de GitHub o claves de API de LLM, lo que podría llevar a un acceso no autorizado a recursos privados y abuso financiero."
