Rapid7 finds 62% of exploited vulnerabilities require no user interaction in Q2 2026
Rapid7's Q2 2026 threat landscape report shows 62% of exploited vulnerabilities required no user interaction. High/critical disclosures doubled YoY to 8,539, with PoC code up 76%. Ransomware victims rose in India and Thailand, while state-aligned actors targeted critical infrastructure.

Rapid7 Inc (NASDAQ: RPD) released its Quarterly Threat Landscape Report on August 18, 2026, revealing that 62% of newly exploited vulnerabilities in the second quarter were "holy grail" flaws that could be exploited over a network without authentication or user interaction. The findings highlight a shift toward automated attack chains, where the window between vulnerability disclosure and active exploitation has collapsed.
High and critical vulnerability disclosures doubled year-over-year to 8,539, while newly exploited vulnerabilities jumped by up to 40%. This surge in exposure is compounded by an increase in publicly available proof-of-concept (PoC) code, which rose 12% quarter-over-quarter and 76% year-over-year, expanding the pool of tools attackers can quickly turn into real-world attacks.
What the Numbers Show
The data reveals a divergence between disclosure volume and exploitability. While high and critical disclosures doubled year-over-year, the proportion of these flaws that are zero-click (62%) suggests that traditional patching models based on static severity scores are increasingly ineffective. The simultaneous 247% year-over-year increase in disclosures involving missing authentication (from 45 to 156) indicates that attackers are prioritizing low-effort entry points over complex exploits.
| Metric | Q2 2026 Data | Change |
|---|---|---|
| Zero-click exploited vulnerabilities | 62% of total | N/A |
| High/critical disclosures | 8,539 | +100% YoY |
| Newly exploited vulnerabilities | N/A | Up to +40% |
| Proof-of-concept code volume | N/A | +76% YoY |
| Missing authentication disclosures | 156 | +247% YoY |
Christiaan Beek, Vice President at Rapid7 Labs, stated that security teams relying on periodic patch cycles are "subsidizing the attackers' R&D." He emphasized moving beyond static CVSS scores to focus on reachable and exploitable exposures.
Ransomware and Geopolitical Threats
Ransomware activity remained concentrated but expanded geographically. The United States accounted for 881 listed ransomware victims, approximately nine times the 99 recorded in Germany. India and Thailand entered the top 10 countries for victims, indicating that ransomware affiliate programs are extending beyond historically prominent U.S. and European targets.
State-aligned campaigns from Iran, North Korea, and Russia targeted critical infrastructure and enterprise sectors. Key tactics included exploiting SOHO edge routers for DNS hijacking and actively targeting operational technology and industrial control systems.
How will the rise in zero-click vulnerabilities accelerate enterprise adoption of Extended Detection and Response (XDR) and behavior-based analytics over traditional signature-based patching?
What regulatory or compliance changes might emerge in response to the 247% surge in missing authentication flaws, particularly regarding mandatory security baselines for critical infrastructure?
Could the geographic expansion of ransomware targets to India and Thailand drive increased demand for localized cybersecurity insurance products and regional incident response teams?
