CVE-2026-45805 Details
Description
Penpot is an open-source design tool for design and code collaboration. Prior to 2.15.0, Penpot MCP's mcp/packages/server/src/ReplServer.ts bound the ReplServer to 0.0.0.0:4403 and exposed an unauthenticated /execute endpoint that passed the code field to PluginBridge.executePluginTask(), allowing anyone on the network to execute JavaScript on the server. This issue is fixed in version 2.15.0.
A remote code execution vulnerability has been identified in Penpot versions prior to 2.15.0. The issue arises in the MCP module's ReplServer, which binds to all network interfaces (0.0.0.0) and exposes an unauthenticated '/execute' endpoint. This allows any network user to POST arbitrary JavaScript, which is then executed on the server. The vulnerability was introduced because the ReplServer was not properly configured to bind only to localhost, leaving it accessible from any machine on the network.
Users can update to Penpot version 2.15.0 or later, where this vulnerability has been fixed. The update process can be done by downloading the latest version from the Penpot GitHub releases page.
