# CVE-2026-117561: sf-mcp through 1.3.2 OS Command Injection via Salesforce CLI Flag Values

- Exploited (CISA KEV): no
- Published: 2026-10-27
- CVSS: 8.5 HIGH (v4.0)
- EPSS: 0.7% (51th percentile)
- CWE: CWE-78

Codefriar sf-mcp through 1.3.2 contains an OS command injection vulnerability that allows attackers to execute shell commands by supplying crafted Salesforce CLI tool flag values. Because escapeValue() in src/utils.ts fails to neutralize backticks, $() substitution, and other shell metacharacters, these values reach execSync in executeSfCommand and run as the MCP server user.

"No public claim" means no vendor statement names this CVE; "Before feed history" means the CVE is older than the vendor feed. In both cases generic rules may still block it.
