Vulnerability Disclosure Program (VDP)

Overview

Vulnerability Disclosure Program (VDP) is a structured program that tells external researchers how to report suspected vulnerabilities safely and defines scope, communication, legal expectations, triage, remediation, and coordinated disclosure. A VDP is not necessarily a paid bug bounty; compensation, eligibility, testing permissions, and reward decisions may differ. It should be interpreted alongside Vulnerability Management, which may affect the same workflow without representing the same control, event, or risk.

Without a clear channel, researchers may disclose publicly, reports may be lost, unsafe testing may occur, and organizations may respond inconsistently or threaten good-faith reporters.

Organizations should publish scope and safe-harbor language, provide a monitored contact, secure report intake, acknowledge quickly, prioritize findings, coordinate fixes, and communicate closure.

Retain reporter contact where provided, affected asset, reproduction steps, severity, scope decision, communications, remediation owner, fix evidence, disclosure date, and lessons learned.

Assessment of Vulnerability Disclosure Program (VDP) should trace Vulnerability Disclosure Program (VDP) is a structured program that tells external researchers how to report suspected vulnerabilities safely and defines scope, communication, legal expectations, triage, remediation, and coordinated disclosure from prerequisite and entry point through observable impact on the affected service. A theoretical weakness or scanner result involving communication, legal expectations, and triage should not be reported as exploitation without corroborating logs, transactions, or configuration evidence. Prevention, detection, containment, and recovery for the Vulnerability Disclosure program should be tested against the architecture associated with communication, legal expectations, and triage.

Retesting for Vulnerability Disclosure Program (VDP) should reproduce the Vulnerability Disclosure program involving communication, legal expectations, and triage, examine adjacent paths, and verify the conditions for safely returning the affected service to normal operation.
