Vulnerability Disclosure Policy


Deutsche Post DHL Group cares about information security. We are committed to maintaining the confidentiality, integrity and availability of Deutsche Post DHL Group systems and information to ensure the trust and confidence of our customers.

Therefore, the security of our online platforms and applications is of great importance to us. We ask that you disclose information security issues in a responsible way and in accordance with this Responsible Disclosure Process. We will then validate and fix vulnerabilities following our vulnerability management program.

Safe harbor statement

If you make a good faith effort to comply with this policy during your security research, we will consider your research to be authorized. We will work with you to understand and resolve any vulnerabilities found quickly, and Deutsche Post DHL Group will not recommend or pursue legal action related to your research. Should legal action be initiated by a third party against you for activities that were conducted in accordance with this policy, we will make this authorization known.

Important guidelines

Under this policy, “research” means activities in which you:

  • Notify us as soon as possible after you discover a real or potential security issue
  • Avoid privacy violations, confidentiality breaches, degradation of user experience, disruption to production systems, and destruction or manipulation of data
  • Do not include any sensitive or personal data in the disclosed vulnerability report
  • Only use exploits to the extent necessary to confirm a vulnerability’s presence. Do not use any exploit to compromise or exfiltrate data, establish command line access and/or persistence, or to pivot to other systems
  • Provide us a reasonable amount of time to resolve the issue before you disclose it publicly. Any disclosure shall happen after Deutsche Post DHL Group confirmed that the issue is fixed.

Once you’ve established that a vulnerability exists or encounter any sensitive data (including personally identifiable information, financial information, or proprietary information or trade secrets of any party), you must stop your test, notify us immediately, and not disclose this data to anyone else.

Test methods

The following test methods are not authorized:

  • Network denial of service (DoS or DDoS) tests or other tests that impair access to, respectively damage a system or data
  • Physical testing (e.g., office access, open doors, tailgating), social engineering (e.g., phishing, vishing and telephone calls), or any other non-networked vulnerability testing
  • Full red-team penetration testing that continue after a vulnerability was found and leads to the compromise of our systems

We would ask you to avoid notifying us of the following types of issues:

  • Missing cookie flags and web application security headers
  • Form spamming
  • UI and UX bugs and spelling mistakes
  • Open ports
  • SSL/TLS misconfigurations
  • DKIM & SPF misconfigurations
  • Grammar and spelling mistakes
  • Issues that have already been published on Bitsight or similar platforms


This policy applies all Deutsche Post DHL Group Systems, explicitly to the following systems and services:

  • *
  • *
  • *

Any service not expressly listed above, such as any connected services, are excluded from the scope and are not authorized for testing. Additionally, vulnerabilities found in systems from our vendors fall outside of this policy’s scope and should be reported directly to the vendor according to their Vulnerability Disclosure Policy (if any). If you aren’t sure whether a system is in scope or not, contact us at before starting your research.

Though we develop and maintain other internet-accessible systems or services, we ask that active research and testing only be conducted on the systems and services covered by the scope of this document. If there is a particular system not in scope that you think merits testing, please contact us to discuss it first. We will increase the scope of this policy over time.


What we would like to see from you:

To help us triage and prioritize submissions, we recommend that your reports:

  • Describe the location (URL) of the vulnerability that was discovered and the potential impact of exploitation.
  • Offer a detailed description of the steps needed to reproduce the vulnerability (proof of concept scripts or screenshots are helpful).
  • Are in English, if possible.

Please send your reports to

What you can expect from us:

When you choose to share your contact information with us, we commit to coordinating with you as openly and as quickly as possible.
