JUnit Failure Fingerprint

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward JUnit test-failure summarizer with no hidden network, persistence, or privilege behavior found.

Install is reasonable for CI/test triage. Use a narrow JUNIT_GLOB such as an artifacts or test-results directory, and review JSON/text output before uploading it because stack traces and failure messages may include secrets from your tests.

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

Finding
The skill invokes scripts that read JUnit XML files via a configurable glob, but the manifest does not declare any explicit tool scope such as permissions or allowed-tools. In an agent environment, undeclared file-read capability can lead to overbroad access, making it easier for the skill to inspect unintended files if inputs are manipulated or defaults are too broad.
