# CI/CD Pipeline Security Audit

This document outlines the findings of a security audit of the CI/CD pipeline.

## Summary of Findings

| Workflow | Finding | Severity |
|---|---|---|
| `ai-worker.yml` | Secrets Exposure | High |
| `ai-worker.yml` | Command Injection | High |
| `ai-worker.yml` | Third-Party Risk | Medium |
| `auto-label.yml` | Code Injection | High |
| `contributor-ci.yml` | Incomplete Security Scans | Medium |
| `jules-dispatch.yml` | Overly Permissive Scopes | Low |

## Detailed Findings

### 1. ai-worker.yml

**Vulnerability:** Secrets Exposure
- **Description:** The `GEMINI_API_KEY` is exposed in the `env` block, making it accessible to shell commands and increasing the risk of leaks.
- **Severity:** High

**Vulnerability:** Command Injection
- **Description:** The workflow is vulnerable to injection attacks through the `steps.diff.outputs.diff` variable, which can be manipulated by contributors.
- **Severity:** High

**Vulnerability:** Third-Party Risk
- **Description:** The use of `actions/github-script` introduces a third-party dependency that could be compromised.
- **Severity:** Medium

### 2. auto-label.yml

**Vulnerability:** Code Injection
- **Description:** The `github-script` action is susceptible to injection from issue titles and bodies, which can be exploited by malicious actors.
- **Severity:** High

### 3. contributor-ci.yml

**Vulnerability:** Incomplete Security Scans
- **Description:** The workflow includes placeholder steps for linting and security scans but lacks concrete implementations, leaving the pipeline exposed.
- **Severity:** Medium

### 4. jules-dispatch.yml

**Vulnerability:** Overly Permissive Scopes
- **Description:** The workflow grants broad `write` permissions for `contents`, `pull-requests`, and `issues`, violating the principle of least privilege.
- **Severity:** Low

## Mitigation Strategies

- **Secrets Management:** Use encrypted secrets and avoid exposing them in the `env` block.
- **Input Sanitization:** Sanitize all inputs from contributors to prevent injection attacks.
- **Third-Party Dependencies:** Pin third-party actions to a specific commit hash to prevent supply chain attacks.
- **Security Scans:** Implement static and dynamic security scanning tools in the CI/CD pipeline.
- **Least Privilege:** Grant the minimum required permissions to each workflow.
