- We respond within 2 business days.
- We process reports within 5 business days after our initial response.
- We may extend the processing time, but you will be informed about any delays.
- We determine the reward amount within 5 business days after processing.
- We will do our best to keep you informed about the progress of your report.

## Rules for You

- Be an ethical hacker and respect the confidentiality of other users.
- Avoid compromising privacy, deleting data, or disrupting or degrading our services.
- When registering a test account for Megamarket research, please use the word "Standoff" in the “Last Name” field to prevent your account getting potentially blocked.
- Automatic scanning tools must be limited to 30 requests per second per target host, counting all tools and threads combined.
- Review these program rules before beginning your research.
- Report vulnerabilities clearly and efficiently.

**Disclaimer:** Megamarket uses the AntiDDoS/antibot protection service ServicePipe. Detection of the header **X-SP-CRID** or functions like **get_cookie_spsc() | _.spsc_** indicates that you are viewing a placeholder page from ServicePipe.
## Scope
**Level 1**  
megamarket.ru  
mgate-grpc.megamarket.ru
mgate-grpc.sbermegamarket.ru  
partner.megamarket.ru

**Level 2**  
`*.sbermegamarket.ru`
`*.megamarket.ru` 

Within Level 2 scope, only vulnerabilities in server-side analytics APIs and integrations that directly interact with our infrastructure (for example, endpoints for sending/receiving analytics, configuration APIs, server-side endpoints) are eligible for rewards.  
Landing pages, static marketing pages, Tilda/WordPress pages, and widgets are not rewarded.
The maximum reward for vulnerabilities found in Level 2 services is up to 20,000 RUB. Such cases will be evaluated individually based on severity and the importance of the domain.

## Megamarket’s Commitments
Megamarket commits to:
- Prioritize security tasks and promptly address identified vulnerabilities.
- Respect researchers and not impose unjustified restrictions on responsible disclosure.
- Refrain from making unfounded accusations related to research participation.

## Public Disclosure
Public disclosure is allowed by mutual agreement.  
Megamarket will communicate transparently with researchers regarding disclosure timing. Both parties may decide when to publish the report.

## Prohibited Actions
Researchers are **not allowed** to:
- Access, modify, delete, or disclose other users' data without consent. Intentional access to such data is prohibited and may be considered illegal.
- Interfere with other users’ accounts.
- Use vulnerabilities for personal benefit.
- Use testing tools that generate excessive traffic or lead to resource exhaustion attacks.
- Conduct attacks impacting service integrity or availability (e.g., DoS, brute force). Instead, report the issue, and Megamarket’s team will perform verification in a test environment.
- Perform physical attacks on staff, data centers, or offices.
- Conduct attacks using social engineering techniques (phishing, vishing, spam) against clients, partners, or staff.
- Research underlying server infrastructure hosting web applications.
- Disclose vulnerability details before Megamarket’s official public release.
If multiple vulnerabilities are discovered, prepare separate reports for each one.

## RCE Testing Policy
Rules to test vulnerabilities leading to remote code execution (RCE):  
Allowed server actions during RCE testing:
- Executing commands: `ifconfig` (or `ipconfig`), `hostname`, `whoami`, `id`.
- Reading contents of files `/etc/passwd` and `/proc/sys/kernel/hostname` (or `drive:/boot.ini`, `drive:/install.ini`).
- Creating an empty file in your user directory.
Any other actions must be pre-approved by Megamarket’s security specialists.
## SQL Injection Testing Policy
Rules to test vulnerabilities that may lead to SQL injection:  
Allowed queries:
- Retrieving current database name (`SELECT database()`), version (`SELECT @@version`), current user (`SELECT user(), SELECT system_user()`), and hostname (`SELECT @@hostname`).
- Retrieving database schema (`SELECT table_schema`), list of tables (`SELECT table_name`), and column names (`SELECT column_name`).
- Performing mathematical, conversion, or logical queries (including SLEEP) without data extraction other than listed above.
Any additional actions must be **pre-approved** by Megamarket’s security specialists.
## File Upload and Reading Policy
Rules to test vulnerabilities that allow arbitrary file reading or uploading:
Prohibited actions during file uploads:
- Modify, replace, or delete any files on the server (including system files) except those associated with your account or approved user accounts.
- Upload files that can cause denial of service (e.g., large files).
- Upload malicious files (malware, spyware, etc.).

If arbitrary file reading on the server is possible, only read the following:  
`/etc/passwd`, `/proc/sys/kernel/hostname`, or (`drive:/boot.ini`, `drive:/install.ini`).  
All other actions must be **pre-approved** by Megamarket’s security specialists.
