### Special Test Scenarios

The program includes **special scenarios** that are eligible for a **maximum reward** of **1,000,000 RUB**.

**Unauthorized Access to a Seller Account**

The goal is to gain full access to the test seller account at https://www.wildberries.ru/seller/3941172, associated with the phone number +7 (993) 965-09-70, through the Wildberries Seller Portal at [seller.wildberries.ru](https://seller.wildberries.ru).

**To qualify for this scenario, the following conditions must be met:**

- You provide a **clear and complete reproduction guide**, including the **flag** located in a hidden product card (Products → Product Cards → item tagged with “flag”)
- You demonstrate the ability to **delete an existing product card**: https://www.wildberries.ru/catalog/190622575/detail.aspx

**Unauthorized Access to a Customer Account**

Your objective is to gain full access to the **test customer account** associated with the phone number +7 (993) 965-09-70 on [www.wildberries.ru](https://www.wildberries.ru).

**To qualify for this scenario, the following conditions must be met:**
- You successfully obtain **unrestricted access** to all core features of the test customer's personal account
- You provide a **detailed step-by-step reproduction guide**, including the **name or details of a product** listed in the “Favorites” section: [https://www.wildberries.ru/lk/favorites](https://www.wildberries.ru/lk/favorites)
- You demonstrate the ability to **change the account holder’s name** to **cjaJKxIYIFGTx2Ew**

**Unauthorized Financial Gain**

This scenario aims to demonstrate the possibility of unauthorized financial gain resulting from the exploitation of vulnerabilities in Wildberries services.

**To qualify for this scenario, the following conditions must be met:**
- You achieve one of the following:
	- Arbitrary crediting of funds to your own balance
	- Unauthorized withdrawal of funds from another user’s balance or from the company’s internal accounts
- You provide a detailed reproduction guide, including a working exploit that demonstrates financial impact in the range of **1,000 to 2,500 RUB**
- The vulnerability, if scaled, could result in **direct financial damage to Wildberries exceeding 500,000 RUB**

Only scenarios based on **technical vulnerability exploitation** are eligible for this category. The following are explicitly **out of scope** and will not be considered:
- Use of **social engineering** or **phishing techniques**
- Fraud schemes or manipulation of business logic unrelated to security flaws
- The presence of **significant time or resource constraints** (e.g., the need for a large number of accounts)
- Participation in **promotional campaigns** or any **marketing activities**
- Repetition of **micro-gains** to accumulate significant damage (e.g., a bug grants 5 rubles and is exploited a thousand times).

### Testing Rules

- You may only use your own accounts or accounts of users who have **explicitly given their consent** for the purpose of participating in this program.
- Accessing third-party accounts or any confidential information without authorization is strictly **prohibited**.
- Any activity that could negatively impact Wildberries services, infrastructure, customers, or partners is **forbidden**. This includes, but is not limited to:
	- Social engineering
	- Phishing
	- Denial-of-Service (DoS) attacks
	- Physical tampering with infrastructure
- Proof of Concept (PoC) should be limited to the **minimum necessary** to demonstrate the issue. If the test may affect other users or system stability, you must contact Wildberries for **prior approval**. **Further exploitation of vulnerabilities is strictly prohibited**.
- Automated scanning tools must be throttled to a **maximum of 10 requests per second**.

### Out-of-Scope Issues

We only accept reports that describe **real security vulnerabilities**. The following are **examples of issues that are out of scope** and will not be considered valid:

**General exclusions**

- Bugs or issues that are not related to security
- Low-likelihood or purely theoretical attacks without evidence of exploitability
- Disclosure of public or non-sensitive user information
- Use of outdated or potentially vulnerable software without a working exploit
- Phishing, social engineering, or any scenario that requires physical access to the victim
- Disclosure of technical or low-sensitivity data (e.g. product version, software stack)
- Raw output from vulnerability scanners or other automated tools
- The ability to upload malicious files without actual execution or impact

**Web Application Exclusions**

- Self XSS
- XSS and HTML injection on \*.wbbasket.ru subdomains
- Vulnerabilities affecting only outdated or unsupported browser versions
- CSRF on non-critical actions
- Clickjacking
- Open Redirect without a clear attack vector (e.g., no token theft or credential leak)
- Publicly accessible metrics (e.g., Prometheus, pprof)
- Exposure of client-side API keys intended for public use (e.g., Dadata, Yandex Maps)
- Absence of recommended security mechanisms (e.g., HTTP security headers, cookie flags, CSRF protection)
- Weak or misconfigured TLS/SSL settings
- Lack of metadata stripping in uploadable files
- SSRF limited to DNS queries only
- Denial-of-service (DoS) attacks
- User enumeration
- Sending spam via email or push notifications
- Circumventing brute-force protections (e.g., by rotating IPs or bypassing CAPTCHA)
- Access to low-privilege or test accounts without meaningful impact

**Mobile Application Exclusions**

- Possibility of reverse-engineering the mobile app
- Lack of detection for rooted or jailbroken devices
- Absence of SSL certificate/key pinning
- Absence of protective flags in native libraries
- Vulnerabilities that require the presence of malware, root access, or a jailbroken device for exploitation
- Attacks that require man-in-the-middle (MITM) interception of someone else's traffic or physical proximity to another user's device (e.g., via NFC, Bluetooth, or Wi-Fi)

### Report Requirements

Each report must describe a single vulnerability or a chain of related vulnerabilities and must include:

- A clear description of the vulnerability
- Step-by-step reproduction instructions
- An assessment of the potential impact (severity)

Additionally, the report must contain:

- The URL of the affected application
- The type of vulnerability
- Screenshots or video recordings that confirm the issue and demonstrate the reproduction steps

Failure to meet the minimum requirements may result in a **reduced reward**. If the report lacks sufficient information to verify the vulnerability, **no reward will be issued**.

### Duplicate Reports

We reward only the **first valid report** for a given vulnerability — provided that it contains sufficient information to reproduce the issue. Any subsequent reports describing the same vulnerability will be marked as duplicates.

Reports involving **similar attack vectors** may also be considered duplicates if the security team determines that a single report provides enough information to fix all related issues.

A duplicate may refer to a submission from another researcher or from Wildberries' internal security team.

**Publicly known 0-day or 1-day vulnerabilities** may be considered duplicates if our team is already aware of them through public sources.

### Reward Ranges

Rewards are issued only for **previously unknown** security vulnerabilities that meet all conditions outlined in this policy. The table below shows approximate reward ranges based on severity and asset tier:

| Severity | Tier 1 | Tier 2 |
| -------- | ------------------- | --------------------- |
| Critical | 200,000₽ – 500,000₽ | 100,000₽ – 250,000₽ |
| High | 60,000₽ – 200,000₽ | 30,000₽ – 100,000₽ |
| Medium | 20,000₽ – 60,000₽ | 10,000₽ – 30,000₽ |
| Low | 5,000₽ – 20,000₽ | 5,000₽ – 10,000₽ |


All reward decisions are made at the discretion of the Wildberries security team, based on severity, exploitability, business impact, and report quality.
