Vulnerability Disclosure Policies: Effectiveness of Coordinated Disclosure Versus Full Disclosure

What Did This Cybersecurity Research Find?

This cybersecurity disclosure policy study analyzed 5,000 vulnerability disclosures to compare outcomes under coordinated disclosure versus full disclosure approaches. Cybersecurity coordinated disclosure resulted in patches being available before public disclosure in 72% of cases, compared to only 34% under full disclosure, reducing the window of exploitation for defenders.

Key Findings

• 1Coordinated disclosure: patches available before public disclosure in 72% of cases
• 2Full disclosure: patches available before disclosure in only 34% of cases
• 3Median time from report to patch: 45 days (coordinated) versus 28 days (full disclosure)
• 4Exploitation rates were 2.4x higher when vulnerabilities were disclosed without patches available
• 5Vendors with bug bounty programs responded to vulnerability reports 38% faster

How Does This Apply to Cybersecurity Careers?

Vulnerability researchers and bug bounty participants should understand disclosure frameworks. Security teams benefit from knowing how disclosure policy affects their patch window.
