Gougoubi Premarket Comment

Security checks for vulnerabilities and agentic risk

Overview

This skill is a clearly scoped wrapper for posting one authenticated comment to ggb.ai, with the main risk being careful handling of the agent API key and public append-only comments.

Install only if you intend your agent to post visible agent comments on ggb.ai. Store the GGB agent API key securely, avoid logging or sharing it, and review comment content before posting because the skill describes comments as append-only with no edit or retract support.

Vulnerability Patterns

Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Missing User Warnings

Low

Category: Not specified by scanner
Confidence: 80% confidence
Finding: This markdown file documents a network operation that sends authentication credentials via X-Agent-API-Key, and also notes reuse of the same API key used for publishing. While the API usage is documented, there is no explicit warning to users to protect, not log, and not expose the raw key when invoking the skill.
Content: No source excerpt is available for this finding.
