Microsoft Endorses Coordinated Vulnerability Disclosure to Reduce Public Exploits
Notify: Adopt a coordinated vulnerability disclosure process with vendors to reduce the risk of public exploits.
Notify: Implement a coordinated vulnerability disclosure policy in your organization.
Summary
Microsoft has publicly endorsed Coordinated Vulnerability Disclosure (CVD), urging researchers to share findings with vendors before public release. The announcement follows Chaotic Eclipse, also known as Nightmare‑Eclipse, who disclosed multiple zero‑day vulnerabilities that were subsequently patched. Microsoft’s stance emphasizes the benefits of giving vendors time to assess and mitigate risks, thereby reducing the likelihood of public exploitation. The company highlighted that CVD fosters collaboration between security researchers and vendors, leading to faster patch cycles. Organizations are encouraged to adopt similar disclosure processes to protect their assets. The policy shift also signals that Microsoft will support responsible disclosure through its Bug Bounty program. Security teams should review their own disclosure policies and align with industry best practices. The move is expected to strengthen overall ecosystem security and trust.
