Responsible Vulnerability Disclosure Guidelines

The security team at Cigna strongly believes that collaboration with the security community is key to maintaining secure environments for all of our clients, members, and partners. If you believe you have discovered a security vulnerability on a Cigna, or any of its subsidiaries or affiliates, website, mobile application, or other property, we strongly encourage you to inform us as quickly as possible. Disclosures may be made to:

Cigna’s Responsible Disclosure Program is governed by these Responsible Vulnerability Guidelines (the “Guidelines”). By submitting a vulnerability to Cigna, you agree to be bound by these Guidelines.

Scope: Software Built by Cigna

Our Responsible Disclosure Program relates only to applications built by Cigna, its subsidiaries, and affiliates. For third party built applications, please reach out to relevant third parties.

Only security vulnerabilities should be reported through this program.

Vulnerabilities related to Cigna and its subsidiaries are in scope.

The following are out of scope of Cigna’s Responsible Disclosure Program, do not qualify as valid vulnerabilities under these Guidelines, and should not be reported:

  • Outdated versions of libraries or other components
  • Self-XSS
  • Missing DNS security configurations (e.g. SPF records, DKIM, etc.)
  • Missing or misconfigured HTTP headers (e.g. HSTS, X-Frame Options, CSP, etc.)

Researcher Guidelines

The privacy of our clients, members, and partners must be maintained during the disclosure of any vulnerability.

This page includes instructions on how to securely report vulnerabilities to Cigna’s security team. Cigna does not accept disclosures that do not follow these Guidelines.

We ask you to:

  • Do not delete any data hosted by Cigna or its subsidiaries or affiliates.
  • Do not access any data or applications that are not necessary to show impact.
  • Do not perform denial of service attacks, disrupt services, or degrade internal or external services.
  • Do not exfiltrate any data during your research.
  • Any confidential information obtained through this research remains the confidential information of Cigna, and its subsidiaries or affiliates as applicable, and is not to be shared with any external parties. Any sensitive (e.g. protected health information or personally identifiable information) obtained through this research should be kept for only as long as necessary to complete the research and must be securely deleted upon resolution of the vulnerability and/or at the direction of Cigna.
  • Do not run any automated tools against our servers.
  • Do not try to abuse our servers' resources, including but not limited to, sending unsolicited or unauthorized email.
  • Social engineering attacks including but not limited to phishing are out of scope.
  • Please provide us a minimum of 90 days from the date we acknowledge receipt of your disclosure to review and remediate reported issues. After this 90 day period, you may publicly disclose your research around the vulnerability, with the exception of any personally identifiable information or protected health information which must at all times remain confidential even after remediation.
  • You acknowledge and agree that there may be situations where Cigna has a reasonable and legitimate interest in understanding the nature of any public disclosure you may make. When reasonable under the circumstances, you agree to work together with Cigna to coordinate any such public disclosure.
  • Only publicly disclose vulnerabilities after remediation in compliance with these Guidelines.
