GHSA-4h5r-5jm8-jxjm
gemini-mcp-tool vulnerable to OS command injection and @file exfiltration via prompt quoting (CVE-2026-0755)
Quick fix
GHSA-4h5r-5jm8-jxjm — gemini-mcp-tool: upgrade to the fixed version with the command below.
npm install gemini-mcp-tool@1.1.6Details
Untrusted prompt input could reach the Gemini CLI @file parser, allowing read/exfiltration of arbitrary local files (@/etc/passwd, @~/.ssh/id_rsa, @../../secret). On Windows, unquoted cmd.exe metacharacters could break out into OS command injection.
Fix (1.1.6): removed the broken shell:false double-quote wrapping; added assertSafeFileReferences() to contain @file refs to the working directory; hardened Windows cmd.exe argument quoting.
