CyberRota Analysis
AI-GeneratedThe yutu AI toolkit for managing YouTube channels is vulnerable due to improper handling of file parameters in its caption-download feature, allowing an attacker to write files to any writable path outside the designated confinement boundary. This can lead to overwriting critical application files, potentially resulting in persistent code execution or denial of service. Organizations using versions prior to 0.10.9 should prioritize updating to mitigate these risks, especially if they operate with default authentication settings.

Original NVD Description
yutu is an AI-powered toolkit for managing and growing YouTube channels. Prior to 0.10.9, the caption-download MCP tool accepts a caller-controlled file parameter through cmd/caption/download.go and passes it to Caption.Download() in pkg/caption/caption.go, where os.Create() creates or truncates that path without using the pkg.Root confinement boundary backed by YUTU_ROOT. A principal able to invoke caption-download, including a local HTTP client when the MCP server runs with its default authentication-disabled configuration, can write downloaded caption bytes to any path writable by the yutu process outside YUTU_ROOT. This can overwrite application files, configuration, shell startup files, logs, or data and can cause persistent code execution or denial of service depending on the selected writable target. Live caption retrieval also requires usable service credentials and an accessible caption identifier. This issue is fixed in version 0.10.9.
