Keyapi Amazon

Security checks for vulnerabilities and agentic risk

Overview

This skill is coherent for Amazon KeyAPI research, but its setup helper stores an API token persistently in shell profile files with insufficient warning and controls.

Install only if you are comfortable with a local helper that can write your KeyAPI token into a shell startup profile in plaintext. Prefer setting KEYAPI_TOKEN only for the current shell session or using a dedicated credential store, and avoid passing tokens on the command line.

Vulnerability Patterns
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The script persists KEYAPI_TOKEN into the user's shell profile, causing long-lived storage of a sensitive credential in plaintext. While this may be intended as a convenience setup step, it exceeds the immediate needs of a marketplace-analysis skill and increases exposure through profile-file disclosure, backups, shared accounts, and accidental commits or support-file sharing.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The interactive prompt uses rl.question() on standard input, so the token is visibly echoed as the user types, and the script does not warn that the secret will also be persisted to the shell profile. This creates unnecessary secret exposure to shoulder-surfing, terminal logs/recordings, and user misunderstanding about where the credential is stored.

Context-Inappropriate Capability

Confidence
84% confidence
Finding

The manifest describes a skill for exploring Amazon marketplace data via the KeyAPI REST API. While using a token is expected, this implementation goes beyond simple request handling by inspecting the user's shell startup files and environment to recover credentials, a capability not stated in the purpose and not directly tied to marketplace analysis itself.
