TL;DR: The 2026 Verizon DBIR says exploitation of vulnerabilities rose to 31% of initial access vectors while credential abuse fell to 13%, and only 26% of critical KEV flaws were fully remediated in 2025, according to Veracode’s summary of the report. The signal for practitioners is that remediation speed, not awareness, is now the limiting control.
Editorial analysis by NHI Mgmt Group, based on content published by Veracode: “What the 2026 Verizon DBIR Reveals About the State of Application Security”.
By the numbers:
- Exploitation of vulnerabilities rose to 31% of initial access vectors in the 2026 Verizon DBIR.
- Credential abuse fell to 13% of initial access vectors in the 2026 Verizon DBIR.
- Only 26% of critical vulnerabilities in CISA’s KEV catalog were fully remediated by organizations in 2025.
Key questions
Q: What breaks when application vulnerabilities are not remediated quickly?
A: Attackers gain more time to move from a small code weakness to data theft, privilege abuse or service disruption.
Q: Why do unresolved code flaws increase breach risk even when IAM is strong?
A: Strong IAM limits credential abuse, but it does not remove application defects that create their own footholds.
Q: What are the signs that vulnerability management is not working well enough in an enterprise?
A: Common warning signs include long remediation cycles, weak visibility into where vulnerabilities exist, and inconsistent prioritisation of high-risk findings.
Practitioner guidance
- Rebalance AppSec and IAM priorities Shift governance focus toward unpatched code paths, reachable services, and fix-age rather than relying on credential controls as the main breach-prevention layer.
- Track remediation by exposure window Measure how long critical flaws remain exploitable after discovery, and use that metric in executive reporting instead of counting findings alone.
- Create a KEV triage path Route Known Exploited Vulnerabilities into an accelerated ownership process so critical issues are assigned, verified, and closed without waiting for normal backlog cycles.
Bottom line: The report shows a structural shift in attack economics, with exploitable application flaws becoming a more attractive route than stolen credentials.

Application vulnerability exposure has become a governance problem, not just a code-quality problem. The report shows that exploitation is now displacing credential abuse as the leading access path, which means security teams can no longer treat AppSec as a secondary control layer. If the organisation cannot reduce exposure before release or shortly after discovery, the vulnerability itself becomes the standing access condition. Practitioners should treat fix velocity as a governance outcome, not a developer productivity metric.
A few things that frame the scale:
- Stolen credentials were involved in 22% of breaches overall and in 88% of basic web application attacks, according to Verizon's 2025 Data Breach Investigations Report.
A question worth separating out:
Q: How should security teams respond when known exploitable flaws keep recurring?
A: Teams should treat recurring exploitable flaws as a governance and prioritisation problem, not just a scanning problem. The right response is to tighten ownership, force faster remediation for KEV-listed issues, and block release paths that repeatedly reintroduce the same weakness. The objective is to shorten the period in which a known flaw can be used operationally.
