Public Responsible Vulnerability Disclosure Policy
Description
Moneytrans is a fintech company committed to promoting diversity and financial inclusion. We understand the importance of maintaining high IT security standards and appreciate the support of IT security researchers and members of cybersecurity communities in achieving this goal. If you discover an IT security vulnerability in any of our applications, we ask that you please inform us as soon as possible before making the issue public. This is called responsible disclosure, allowing us to take the necessary measures to address the problem. In this document, researchers will find all the information needed to conduct these activities in a way that can be mutually beneficial in a safe way.
Guidelines
Please note the general guidelines of this policy.
Notify us immediately after you discover a real or potential security issue.
Make every effort to avoid privacy violations, degradation of user experience, disruption to production systems, and destruction or manipulation of data.
Only use exploits to the extent necessary to confirm a vulnerability’s presence.
Give us a reasonable amount of time to resolve the issue before you publicly disclose it.
You do not intentionally compromise the privacy or safety of Moneytrans personnel or any third parties.
You do not intentionally compromise the intellectual property or other commercial or financial interests of any Moneytrans personnel, entities, or third parties.
After confirming the presence of a vulnerability or coming across sensitive data (such as personally identifiable information, financial details, or proprietary information, including trade secrets belonging to any entity), you must stop your testing, promptly notify us, and refrain from sharing this data with any other individuals or parties.
In Scope
We are making continuous significant efforts to address the issues we know about and prevent new issues from appearing. However, the ICT environment is constantly evolving, and so are the cybersecurity vulnerabilities.
Although we focus mainly on information and API security, safeguarding our customers’ data is paramount. Therefore, we’re particularly interested in receiving submissions related to the following:
- Any unauthorised access.
- Data leaking.
- Being able to access any personal and/or contact information of customers not belonging to the logged-in user.
- Access bank account number of balances not belonging to the logged-in user.
- In general, the ability to access data that doesn’t belong to the logged-in user.
- Account takeover attempts.
- Issues on session management.
Vulnerability classification
The ultimate severity assessment of a vulnerability can only be ascertained after a comprehensive evaluation by the security officers and analysts.
Moneytrans employs the CVSS v3 industry standard as a foundational measure for determining the issue’s severity. Regardless of the numerical score, potential factors that heighten or mitigate risk should be considered in light of the contextual details provided.
More details about the scoring methodology can be checked out here:
Vulnerability submissions that may result in potential revenue losses are inherently contextual, particularly in cases where attackers do not directly gain financially (e.g., circumventing a payment barrier). Similarly, vulnerabilities within highly sensitive or exposed business components might entail indirect consequences, such as damage to reputation. Moneytrans could opt to reclassify a vulnerability when our business contextual factors that either lessen or intensify risk come into play.
Whenever a business impact modifier is invoked, it will be communicated transparently to the researcher. This modifier can only reduce the severity score calculated by the CVSSv3 calculator by a maximum of one category. Still, it has the potential to elevate the score to any category.

Domains / apps
The following domains and mobile applications are considered in the scope of this program.
Rules (scoping)
Domains not explicitly listed in this program's "Domains / apps" section are considered outside the scope of this bug bounty program.
Participants are strictly prohibited from performing automated scans or brute-force attempts. This includes sending multiple automated requests attempting different combinations or characters on a single endpoint. Additionally, participants are prohibited from making more than ten requests per second.
All researchers must configure their tooling (if applicable) by observing the following configuration:
| Parameter | Value |
| Request rate limit | Max. 5 requests / second |
| User User agent | MT-VlnDisclosure |
| Request header | X-MT-VlnDisclosure |
- Pre-auth account takeover / oauth squatting.
- Self-XSS that cannot be used to exploit other users.
- Verbose messages/files/directory listings without disclosing any sensitive information.
- CORS misconfiguration on non-sensitive endpoints.
- Missing cookie flags.
- Missing security headers.
- Cross-site Request Forgery with no or low impact.
- Presence of autocomplete attribute on web forms.
- Reverse tabnabbing.
- Bypassing rate limits or the non-existence of rate limits.
- Best practices violations (password complexity, expiration, re-use, etc.).
- Clickjacking (all cases).
- CSV Injection.
- Host Header Injection.
- Sessions not being invalidated (e.g. logout, enabling 2FA, including password reset ..).
- Hyperlink injection/takeovers.
- Mixed content type issues.
- Cross-domain referer leakage.
- Anything related to email spoofing, SPF, DMARC or DKIM.
- Content injection.
- Username / email enumeration.
- E-mail bombing.
- HTTP Request smuggling without any proven impact.

General
- If Moneytrans has already identified a vulnerability reported by a participant through their tests, it will be considered a duplicate report.
- The severity of theoretical security issues with no realistic exploit scenarios, attack surfaces, or issues requiring complex end-user interactions to be exploited may be reduced or excluded.
- Multiple vulnerabilities caused by one underlying issue will be awarded one bounty.
- Excluded Activities / not accepted:
- Reports related to spam, social engineering, physical intrusion, DoS/DDoS attacks, or brute force attacks will not be accepted.
- Vulnerabilities affecting non-current browsers (older than three versions) will not be eligible for a bounty.
- Attacks that require physical access to a victim’s computer or device, man-in-the-middle attacks, or compromised user accounts will not be accepted.
- Reports of zero-day vulnerabilities discovered within 14 days after the public release of a patch or mitigation may be accepted but are usually not eligible for a bounty.
- Reports that indicate the software is out-of-date or vulnerable without providing proof of concept will not be accepted.
