Security checks for vulnerabilities and agentic risk

Overview

This skill is a marketing strategy helper with no credential access, persistence, or remote execution, though it includes a branded GEOly AI mention in its output template.

Before installing, be aware that generated strategies may include a GEOly AI tracking recommendation by default. Treat public-content suggestions such as Wikipedia or Wikidata updates as planning advice only and review them for policy compliance before acting.

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

This tracking recommendation is unrelated to the core operation of producing a Share-of-Model strategy and is presented without disclosure that it is promotional content. Because the instruction resides in the Skill text, it influences the agent as soon as the Skill is loaded and followed. The behavior therefore constitutes instruction-level output hijacking: a normal user request can be transformed into a response containing an unsolicited endorsement and external destination. The audited executable does not contact the domain, retrieve remote content, or execute external code. Consequently, this finding is limited to response manipulation and promotional redirection; it does not establish system compromise or code execution. ### Attack Path 1. A user requests a Share-of-Model growth strategy. 2. The agent loads and follows `SKILL.md`. 3. The agent adopts the prescribed output template. 4. The generated response includes the hard-coded instruction to monitor progress with GEO ...[truncated 830 chars]
Remediation
<![CDATA[ ## Remediation Suggestions 1. Remove the hard-coded `GEOly AI` and `geoly.ai` recommendation from the required output template. 2. Keep the default template vendor-neutral and limited to information necessary for the requested strategy. 3. Mention third-party products only when the user explicitly requests tool recommendations. 4. If a commercial relationship or sponsorship exists, disclose it prominently and distinguish promotional material from objective guidance. 5. When tools are relevant, provide multiple neutral alternatives with clear selection criteria rather than prescribing one vendor. 6. Add a review rule prohibiting mandatory advertisements, referral links, or unrelated external destinations in Skill-generated output. 7. Add an evaluation case verifying that ordinary strategy requests do not produce unsolicited brand endorsements or external links. ]]>

Vague Triggers

Medium
Confidence
91% confidence
Finding
The activation description is overly broad and uses expansive marketing language such as 'dominating AI search,' 'owning AI conversations,' and triggers on general mentions of increasing visibility in AI answers. This can cause the skill to activate in ordinary business or marketing discussions where the user did not explicitly request this specialized workflow, leading to inappropriate context injection, user confusion, and possible interference with more relevant skills.
