Name of the Vulnerable Software and Affected Versions
Penpot versions prior to 2.18.0
Description
In single-user mode, the MCP server plugin WebSocket bridge binds to all network interfaces without requiring authentication. This allows unauthenticated attackers on adjacent networks to connect to the WebSocket port, enabling them to impersonate the Penpot browser plugin, intercept task payloads, and return forged results to the MCP client.
Recommendations
Update to version 2.18.0 or later.
