Detailed vulnerability description
The vulnerability allows a remote user to execute rewritten local code.
The vulnerability exists due to incorrect authorization in the node-host system.run approval mechanism when handling script-runner commands with mutable file operands. A remote user can obtain approval for a benign script-runner command and then rewrite the referenced script on disk to execute rewritten local code.
User interaction is required for operator approval, and the issue affects unrecognized script runners such as tsx and jiti.
