CVE-2026-26029

Estado: AplazadaAlta (7.5)—

sf-mcp-server is an implementation of Salesforce MCP server for Claude for Desktop. A command injection vulnerability exists in sf-mcp-server due to unsafe use of child_process.exec when constructing Salesforce CLI commands with user-controlled input. Successful exploitation allows attackers to execute arbitrary shell commands with the privileges of the MCP server process.

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.

Vector CVSS con UI:R (interacción usuario) y acceso remoto indica ejecución en cliente; CWE-78 (command injection) confirma ejecución de comandos arbitrarios con privilegios del proceso MCP.

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.
