Security audit

Indian Stock Fundamental Analyser

Security checks for vulnerabilities and agentic risk

Overview

This skill is a purpose-aligned Indian stock analysis API wrapper with disclosed external API use and no local execution, persistence, or credential access in the artifact.

Before installing, treat this as a third-party financial analysis API: do not send sensitive portfolio details unless you trust the provider, and verify any BUY/SELL-style output with independent financial judgment. The reviewed artifact does not show local system access or hidden behavior.

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
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
86% confidence
Finding

This is a manifest-style file, so vague-trigger review applies. The title and description describe the skill broadly as stock analysis for Indian stocks, but they do not define any explicit invocation phrases, scope limits, or exclusion conditions, which can make activation criteria ambiguous in systems that infer tool use from manifest text.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill explicitly states it uses real-time web search for analysis but does not warn users that submitted stock tickers or company names may be transmitted to external services. This is a genuine transparency and privacy issue because users may assume analysis is self-contained and not realize their queries are shared with third-party infrastructure.

Natural-Language Policy Violations

Low
Category

Confidence
74% confidence
Finding

The natural-language title and description explicitly constrain the skill to Indian stocks and Indian exchanges. Because no user opt-in or justification is provided in this file, this may constitute a locale-specific policy constraint embedded in the skill metadata.
