Vulnerabilities remain one of the most exploited entry points for cyberattacks. According to the Indusface State of Application Security Report 2026, attacks targeting website vulnerabilities reached 6.29 billion in 2025, up from 4 billion in 2024, a 56% year-over-year increase.

That number is not just a trend line. It means attackers are finding, weaponizing, and exploiting vulnerabilities faster than most security teams can respond. With 131 new CVEs disclosed every day and the median time to exploit now under 5 days, the question for security teams in 2026 is no longer whether vulnerabilities will be targeted, it is whether the right ones are being fixed fast enough.

This article covers the key vulnerability statistics for 2026 across discovery, exploitation, industry impact, and notable CVEs, with a focus on what the numbers mean for how your team prioritizes and responds.

1. Vulnerability Discovery & Disclosure Trends

1. 48,174 new CVEs were published in 2025, marking one of the highest annual totals ever recorded as the attack surface across cloud services, APIs, and software supply chains continues to grow, which reflects the increasing complexity of modern software ecosystems and the growing scrutiny from security researchers worldwide. (National Institute of Standards and Technology – National Vulnerability Database)

2. Attacks targeting website vulnerabilities increased by 56% year over year. highlighting how attackers continue to exploit known application weaknesses. (Indusface State of Application Security report 2026)

3. Vulnerabilities disclosed in 2025 accounted for roughly 15.8% of all known vulnerabilities ever recorded, showing how rapidly the vulnerability ecosystem is expanding. (CVE Program)

4. 131 vulnerabilities were disclosed every day in 2025, forcing organizations to continuously evaluate which vulnerabilities require urgent remediation. For security teams, this constant stream of disclosures makes vulnerability prioritization and automated risk assessment essential.  (NVD Data Analysis)

5. The average daily CVE disclosure rate increased from ~113 per day in 2024 to around 127–131 per day in 2025, highlighting the accelerating pace of vulnerability discovery across modern software ecosystems. (NVD historical CVE statistics), (Zafran Research)

6. January 2025 alone recorded more than 4,200 disclosed vulnerabilities, one of the highest monthly totals driven by coordinated vendor patch releases and research disclosures. (CVE disclosure analysis)

7. By December 2025, the CVE database had grown to more than 320,000 recorded vulnerabilities, making it the world’s largest publicly accessible vulnerability dataset. plays a critical role in threat intelligence, vulnerability scanning tools, and enterprise risk management strategies. (CVE Program)

8. The surge in vulnerability disclosures is placing significant strain on security teams, who must triage thousands of new issues each month. (National Institute of Standards and Technology NVD program updates)

9. API vulnerability exploitation grew by more than 181% in 2025, highlighting the growing risk created by rapidly expanding APIs and limited security testing during development. (Indusface State of Application Security Report)

For security teams, this volume makes automated vulnerability discovery and continuous scanning non-negotiable. Manual triage at 131 CVEs per day is not a sustainable operating model.

2. Severity & Risk Profiles

10. 38% of vulnerabilities disclosed in 2025 were rated High or Critical, meaning more than one-third had the potential to significantly impact systems if exploited, enabling remote code execution, privilege escalation, or authentication bypass in real-world environments. (NVD CVSS statistics)

11. 1,773 vulnerabilities were rated Critical (CVSS 9–10), highlighting the continued discovery of highly dangerous flaws in the first half of 2025 alone. (NVD vulnerability trend analysis)

12. Only about 0.1% of vulnerabilities had detection coverage in open-source security tools, exposing major gaps in community detection capabilities. (Independent vulnerability intelligence research)

13. Severity distribution across vulnerabilities shows ~8.8% Critical, ~36.6% High, ~44.2% Medium, and ~4.1% Low, reinforcing that medium-severity flaws dominate the threat landscape. (NVD CVSS dataset analysis)

14. 293+ “critical gap” vulnerabilities had public exploit code but lacked detection rules, leaving defenders without reliable detection capabilities. (Vulnerability intelligence research)

15. Delayed CVSS scoring continues to affect vulnerability prioritization, making it harder for security teams to determine risk levels quickly. (Sonatype research reported by IT)

With 38% of vulnerabilities rated High or Critical and significant gaps in detection coverage, severity scores alone are not enough. Risk-based prioritization that factors in exploitability and asset exposure is the more reliable signal.

3. Exploitation Patterns & Zero-Day Activity

Attackers increasingly exploit vulnerabilities before organizations can deploy patches, demonstrating the speed of modern exploit development.

16. 159 vulnerabilities were confirmed to be exploited in the wild during Q1 2025, showing how quickly attackers operationalize new vulnerabilities. (Threat intelligence research reported by The Hacker News)

17. 28.3% of exploited vulnerabilities were weaponized within 24 hours of disclosure, dramatically shrinking the patching window for defenders. (Threat intelligence reporting)

18. Known Exploited Vulnerabilities (KEVs) continue to grow steadily, highlighting how frequently attackers target previously disclosed vulnerabilities. (Cybersecurity and Infrastructure Security Agency KEV catalog)

19. 32.1% of exploited vulnerabilities were abused on or before the CVE disclosure date, effectively making them zero-day attacks. (VulnCheck research)

20. PHP Object Injection, File Upload Vulnerabilities, and Blind SQL Injection were among the most common critical web vulnerabilities, showing that traditional web security flaws continue to dominate modern attack surfaces. ((Indusface State of Application Security report)

21. 32% of identified vulnerabilities remained unpatched for more than 180 days, significantly increasing the likelihood that attackers can exploit them before remediation occurs. ((Indusface State of Application Security report, 2026)

22. Around 60% of breaches involved exploiting known vulnerabilities where a patch was already available, highlighting how delayed patching remains one of the biggest security gaps in organizations. (Verizon Data Breach Investigations Report 2025)

23. The median time to exploit a vulnerability is now under 5 days, significantly faster than traditional patch cycles, increasing the risk of exposure for unpatched systems. (Mandiant M-Trends Report)

24. Over 75% of attacks targeting web applications involve exploitation of vulnerabilities in application logic, reflecting a shift toward more targeted, business-logic attacks. (Akamai State of the Internet Security Report)

25. More than 80% of successful cyberattacks leverage vulnerabilities disclosed more than a year earlier, showing that older vulnerabilities remain a primary attack vector. (CISA KEV analysis)

26. Nearly 50% of internet-facing applications contain at least one critical vulnerability, exposing organizations to high-risk exploitation. (Veracode State of Software Security Report)

27. The average time to remediate critical vulnerabilities exceeds 60 days, leaving a significant window for attackers to exploit known weaknesses. (ServiceNow Security Operations Report – https://www.servicenow.com/products/security-operations.html)

28. Over 40% of organizations lack full visibility into their API attack surface, increasing the likelihood of undiscovered vulnerabilities being exploited. (Salt Security State of API Security Report 2025

29. 6235 zero-day vulnerabilities were identified across protected websites in 2025, representing a 2.5× increase compared to 2024, when 2,568 such threats were detected. (Indusface State of Application Security report, 2026)

30. Server-Side Request Forgery (SSRF) and exposed credentials in headers were also among the top critical vulnerabilities, enabling attackers to access internal systems or sensitive data if left unpatched. (Indusface State of Application Security report, 2026)

31. Security misconfiguration and broken authentication ranked among the most common API vulnerabilities, exposing business-critical APIs to unauthorized access and data manipulation. (Indusface State of Application Security report, 2026)

The 5-day median time to exploit means the patch cycle is no longer the primary defense. Virtual patching at the WAF layer buying time while development cycles catch up is now a standard part of a mature vulnerability response program.

4. Industry specific findings

Across industries, vulnerability exploitation reflects how attackers prioritize sectors based on data value and digital exposure. The Indusface State of Application Security Report 2026 highlights clear evidence in how vulnerabilities are targeted across industries.

32. Banking & Financial Services: Vulnerability attacks increased 149% year over year, reflecting how digital banking platforms, payment systems, and customer portals remain prime targets for attackers seeking financial data and transaction access

33. Insurance: The sector recorded a 220% year-over-year surge in vulnerability attacks, the highest among the industries analyzed, as threat actors increasingly target policy management systems and customer-facing applications.

34. Manufacturing: Vulnerability attacks grew by 167%, highlighting the rising risk across connected industrial systems, supply-chain platforms, and operational technology environments.

35. Healthcare: Vulnerability attacks increased by 168.24% in Q1 2025 compared to the previous year, as attackers continue targeting healthcare applications, patient portals, and medical record systems that store sensitive personal data.

Industries seeing the steepest increases share a common thread: expanding digital surfaces with applications that were not built with modern security requirements in mind. Vulnerability management with continuous scanning and runtime protection are the fastest path to closing that gap.

5. Notable CVEs & Real-World Vulnerabilities

The statistics above describe the scale of the problem. These CVEs show what it looks like in practice:

36. Within the first week of disclosure, over 54% of critical vulnerabilities face active exploitation, significantly narrowing the response window for organizations with slow patch cycles (Comparecheapssl). These real-world CVEs show how broader vulnerability trends translate into active attacks, highlighting the types of weaknesses attackers are prioritizing in modern environments.

37. The Angular SSR SSRF vulnerability (CVE-2026-27739) exposed how improper validation of HTTP headers can allow attackers to access internal services and cloud metadata, potentially leading to sensitive data exposure, cloud credential theft, and internal network reconnaissance.

38. CVE-2026-25639, a high-severity Axios vulnerability, demonstrated how prototype pollution in configuration handling can be exploited to trigger application crashes, impacting API availability and causing denial-of-service conditions in backend systems.

39. The WPvivid plugin vulnerability (CVE-2026-1357) showed how widely used WordPress components remain a prime target, enabling unauthenticated remote code execution that can result in full website takeover, data exfiltration, and malicious code deployment.

40. The Ivanti EPMM vulnerabilities (CVE-2026-1281, CVE-2026-1340) highlighted how pre-authentication flaws in enterprise mobility platforms can lead to complete system compromise, exposing sensitive enterprise data, device control systems, and enabling large-scale unauthorized access.

41. The Metro4Shell vulnerability (CVE-2025-11953) in React Native’s development server demonstrated how exposed development environments can be exploited for remote code execution, allowing attackers to compromise developer machines, steal source code, and pivot into internal enterprise networks.

42. CVE-2026-22610, an Angular Template Compiler XSS vulnerability, reinforced the continued risk of improper input sanitization, enabling attackers to execute malicious scripts that can hijack user sessions, steal credentials, and perform unauthorized actions on behalf of users.

43. The Ni8mare vulnerability (CVE-2026-21858) in n8n exposed how automation platforms connected to multiple services can become high-impact attack vectors, allowing attackers to execute system commands, access sensitive integrations, and move laterally across connected environments.

44. CVE-2025-3248 in Langflow highlighted the risks of insecure code execution endpoints, where lack of authentication and sandboxing allowed attackers to run arbitrary Python code, leading to full server compromise, malware deployment, and data theft.

45. The Windows Admin Center vulnerability (CVE-2026-20965) demonstrated how authentication bypass flaws in cloud-integrated management tools can enable lateral movement across systems, potentially resulting in privilege escalation and tenant-wide compromise.

46. CVE-2025-55131 in Node.js revealed how memory handling issues can expose sensitive data such as tokens and application state, increasing the risk of information leakage and exploitation in multi-tenant or untrusted execution environments.

Notable CVEs, These CVEs are not outliers. They reflect the same patterns the statistics describe: fast weaponization, API exposure, unpatched known vulnerabilities, and development environments left unsecured. The organizations that contained these threats quickly were the ones with continuous scanning, virtual patching, and runtime API protection already in place.

What These Numbers Mean for Your Security Posture in 2026

The trend running through every statistic in this report is the same, the gap between when a vulnerability is disclosed and when it is exploited is closing faster than most security teams can respond.

Three areas stand out from the data as the highest-leverage priorities for 2026:

Vulnerability prioritization needs to be faster and more automated with 131 new CVEs every day, manual triage isn’t viable. Teams that rely on CVSS scores alone are working from delayed, incomplete risk signals. Risk-based prioritization that factors in exploitability, exposure, and asset criticality, not just severity is the baseline requirement for 2026.

API attack surfaces are expanding faster than security coverage API vulnerability exploitation grew 181% in 2025. More than 40% of organizations lack full visibility into their API attack surface. Shadow APIs, undocumented endpoints, and APIs developed without security testing are creating exposure that traditional scanning tools don’t cover. Continuous API discovery and runtime monitoring are no longer optional for organizations running modern application architectures.

The patch window is no longer measured in weeks The median time to exploit a vulnerability is now under 5 days. The average time to remediate a critical vulnerability exceeds 60 days. That 55-day gap is where most breaches happen. Virtual patching, applying a protection rule at the WAF layer while development cycles catch up is the most practical way to close that window without slowing down release velocity.

AppTrana addresses all three directly. Continuous vulnerability scanning identifies and prioritizes risk across web applications and APIs. Automated API discovery brings shadow and zombie endpoints under visibility and protection. And SwyftComply applies virtual patches to critical vulnerabilities within 72 hours of discovery, delivering a clean, zero-vulnerability report without waiting for a code fix.

The statistics in this report describe what’s already happening. The organizations that come out ahead in 2026 are the ones treating vulnerability management as a continuous operational function, not a quarterly audit exercise.
