Growing Exposure Debt in Cybersecurity Vulnerabilities

• •Critical vulnerabilities are being resolved 61% faster, but unresolved findings have increased 131%.
• •Vulnerability volume has surged 6.5x in three years, complicating remediation efforts.
• •Traditional remediation models are failing as the gap between threat speed and remediation widens.

Cybersecurity teams are resolving critical vulnerabilities 61% faster than two years ago, but the backlog of valid, unresolved findings has grown by 131% from 2024 to 2026. This phenomenon, termed Exposure Debt, indicates a widening gap between the speed of vulnerability discovery and the ability to remediate them. The HackerOne Security Research Report highlights that while remediation times have improved, the number of open valid reports has surged, leaving security teams overwhelmed. Concurrently, the Qualys report notes a 6.5x increase in vulnerability volume over the past three years, with exploitation timelines collapsing, often occurring before disclosure. This indicates that traditional remediation models are becoming ineffective. The reports emphasize the need for continuous threat exposure management (CTEM) and autonomous risk management to address these challenges effectively.
