computer-use

MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (low risk: 0.10). The computer use skill takes screenshots of the virtual display, which may capture arbitrary outsider-authored text displayed in browser windows or applications, but this constitutes low-risk indirect prompt injection via fetched or viewed content rather than automated message ingestion.

MEDIUM W013: Attempt to modify system services in skill instructions.

• Attempt to modify system services in skill instructions detected (high risk: 1.00). The skill prompt instructs the agent to install system packages, copy and configure systemd service files, and modify system binaries (/usr/bin/xfdesktop), which requires root/sudo privileges and modifies critical system state.
