Responsible Disclosure

Capital One/Discover is committed to maintaining the security of our systems and our customers’ information. We appreciate and encourage security researchers to contact us to report potential vulnerabilities identified in any product, system, or asset belonging to Capital One/Discover.

If you believe you have identified a potential security vulnerability, please submit it pursuant to our Responsible Disclosure Program. Thank you in advance for your submission, we appreciate researchers assisting us in our security efforts.

Responsible Disclosure Program Guidelines

Researchers shall disclose potential vulnerabilities in accordance with the following guidelines:

  • Do not engage in any activity that can potentially or actually cause harm to Discover, our customers, or our employees.
  • Do not engage in any activity that can potentially or actually stop or degrade Discover services or assets.
  • Do not engage in any activity that violates (a) federal or state laws or regulations or (b) the laws or regulations of any country where (i) data, assets or systems reside, (ii) data traffic is routed or (iii) the researcher is conducting research activity.
  • No automated scanning or testing.
  • Do not store, share, compromise or destroy Discover or customer data. If Personally Identifiable Information (PII) is encountered, you should immediately halt your activity, purge related data from your system, and immediately contact Capital One/Discover. This step protects any potentially vulnerable data, and you.
  • Do not initiate a fraudulent financial transaction.
  • Provide Capital One/Discover reasonable time to fix any reported issue, before such information is shared with a third party or disclosed publicly.

By responsibly submitting your findings to Capital One/Discover in accordance with these guidelines Capital One/Discover agrees not to pursue legal action against you. Capital One reserves all legal rights in the event of noncompliance with these guidelines.

Once a report is submitted, Capital One/Discover commits to provide prompt acknowledgement of receipt of all reports (within two business days of submission) and will keep you reasonably informed of the status of any validated vulnerability that you report through this program.

Submission Format

When reporting a potential vulnerability, please include a detailed summary of the vulnerability, including the target, steps, tools, and artifacts used during discovery (screen captures welcome).

Scope

We have listed the assets in scope for this program, however, if you have found a potential vulnerability (excluding the out of scope vulnerabilities listed below) on any product, system or asset you believe belongs to Discover, please submit it through this program as we would like to hear about it.

Out of Scope Vulnerabilities

Certain vulnerabilities are considered out of scope for our Responsible Disclosure Program. Out-of-scope vulnerabilities include:

  • Physical Testing
  • Social Engineering. For example, attempts to steal cookies, fake login pages to collect credentials
  • Phishing
  • Denial of service attacks
  • Resource Exhaustion Attacks
  • Clickjacking on pages with no sensitive actions
  • The submission of form data via HTTP sites
  • Google Maps API key exposure/misconfiguration(s)
  • Zombie links for expired Discover meetings

Please also note that Discover employs third party vendors and some subdomains may be managed by third parties. Security issues found in third-party assets which are not managed by Discover are considered out of scope and should be reported to the affected party directly. When issues reported to the Discover program originate in a different vendor's service, Capital One/Discover reserves the right to forward submissions to the affected party without further discussion. Please be sure to check our publicly published IP ranges and conduct all necessary due diligence to determine ownership of an asset prior to testing.
