Vulnerability Type:T09: Insecure Skill Coding Practices
Risk Level: MediumComplete instruction snippet translated into English:
text - Immediately handle anything that can be automatically repaired.Technical Analysis
The instruction directs the agent to perform automatic remediation but does not define an allowlist of permitted operations, privilege boundaries, approval requirements, validation checks, or rollback procedures. This expands the skill from passive monitoring into potentially destructive system modification.
The package contains no executable implementation, so no specific malicious command or privilege-escalation mechanism is present. Exploitation depends on the tools and operating-system permissions granted to the agent at runtime. If privileged system-management tools are available, an incorrect diagnosis or manipulated monitoring result could cause the agent to execute unsafe corrective actions.
Attack Path
- The skill is loaded with access to system-monitoring and system-management tools.
- A genuine, transient, misclassified, or attacker-induced condition is identified as an anomaly.
- The broad remediation instruction causes the agent to select a state-changing action without requesting user approval.
- The agent performs that action using its existing runtime privileges.
- The action disrupts services, processes, files, or configuration if the diagnosis or remediation choice is incorrect.
Impact Assessment
The maximum impact is limited to the permissions and tools already available to the agent; the skill itself does not obtain additional privileges. With restricted permissions, impact may be negligible or confined to user-owned resources. With administrative permissions, possible consequences include stopping services or processes, changing configuration, modifying or deleting files, and causin ...[truncated 146 chars]

Remediation Suggestions
- Make monitoring and reporting the default behavior; do not perform state-changing remediation automatically.
- Require explicit user confirmation before stopping processes, changing configuration, deleting files, restarting services, or performing other consequential actions.
- Define a narrow allowlist of low-risk automated actions, including exact commands, permitted arguments, target resources, and execution conditions.
- Run the skill with least privilege and separate read-only monitoring permissions from remediation permissions.
- Add precondition validation, dry-run previews, timeouts, post-action health checks, and rollback procedures.
- Record anomaly evidence, selected remediation, authorization, commands executed, and results in an audit log.
- Treat externally influenced monitoring data as untrusted and require corroboration before initiating remediation.
