gemini-mcp-tool vulnerable to OS command injection and @file exfiltration via prompt quoting (CVE-2026-0755)
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | gemini-mcp-tool | >= 1.1.2, < 1.1.6 | 1.1.6 |
Details
As written in the advisory (Markdown source, shown as plain text).
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.
