Security checks for vulnerabilities and agentic risk

Overview

ClawScan marked this skill benign because the reported external API requests appear aligned with its purpose, while noting a privacy disclosure gap and incomplete reference checks.

Consider that store lookups may send your postcode to Scavio, and avoid sharing more location information than needed. The verdict is benign with medium confidence, but Skillspector reports partial analysis: several local references could not be resolved, so the evidence is incomplete.

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
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
Findings (12)

Store-lookup workflow lacks a privacy warning about sending the user's postcode to Scavio.

Output Handling
Confidence
88% confidence
Finding

The workflow instructs the agent to submit a postcode to /stores, which uses the third-party Scavio API. Although the API provider and request format are documented, the skill does not warn the user that their supplied location information will be transmitted to Scavio rather than only to Maisons du Monde.
