curl-to-postman

Security checks for vulnerabilities and agentic risk

Overview

This is a small documentation-only skill for converting pasted curl commands into Postman JSON, with the main caution that copied credentials may be preserved in the output.

Install is reasonable for a curl-to-Postman helper, but redact live Authorization headers, Basic Auth credentials, cookies, API keys, and sensitive body fields before using or sharing generated collections. Imported Postman collections can store whatever secrets were present in the pasted curl command.

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

Finding

The skill explicitly preserves authentication material such as Basic Auth credentials and Bearer tokens when converting curl commands, but it does not warn users that pasted secrets will be carried into the generated Postman collection. This creates a realistic risk of inadvertent credential disclosure, unsafe sharing of exported collections, or storage of live secrets in Postman workspaces and agent transcripts.
