figma-developer-mcp is a Give your coding agent access to your Figma data. Implement designs in any framework in one-shot.
Affected versions of this package are vulnerable to Arbitrary Command Injection via the child_process.exec call using unvalidated user input directly within command-line strings. An attacker can execute arbitrary system commands by supplying crafted input that is unsafely incorporated into shell command execution.
##Workaround
This issue can be mitigated by avoiding the usage of child_process.exec with untrusted input. A safer API such as child_process.execFile can be used, which allows to pass arguments as a separate array to avoid shell interpretation entirely.
