Security audit

create-pr

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward pull-request workflow skill with disclosed repo publishing actions and an approval gate before pushing.

Install this if you want an agent to help publish branches and create PRs. Be aware that phrases like "PR this" or "ship this branch" may invoke it, and review any push approval carefully, especially when auto-complete or auto-merge defaults are configured.

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 metadata description includes very broad activation phrases such as 'create a PR', 'PR this', and 'ship this branch', and even says to use the skill when those phrases appear 'even if they don't explicitly say create-pr skill'. In an agentic environment, this can cause unintended invocation from casual conversation or quoted text, leading the agent into a flow that may review code, inspect repos, and prepare to push or create PRs without the user deliberately selecting this capability.

Vague Triggers

Category
Not specified by scanner
Confidence
88% confidence
Finding

The 'When to use this skill' section repeats short, ambiguous trigger phrases without clear scope constraints or exclusion rules. Because this skill performs high-impact workflow actions downstream, ambiguous routing increases the chance that normal developer chat, examples, or references to PRs invoke the skill and start collecting repo state or steering the session toward publishing behavior.
