CVE-2025-11273Network attack vector

Authenticated command execution via unsanitized OAuth endpoint

Published Oct 4, 2025 · Updated Oct 4, 2025

OS command injection in Verger 1.2.0 through 1.2.10 allows remote authenticated users to execute commands through a malicious MCP server. redirectToAuthorization passes the server-supplied OAuth authorization URL to the Node open function without validating its scheme or neutralizing command syntax. A user must add and activate the malicious MCP server; its crafted authorization metadata then triggers commands on the desktop host without further interaction.
