AI-Assisted Bug Hunting Drives 2026 CVE Disclosures Higher, With Chrome Up More Than Fivefold
Common Vulnerabilities and Exposures, or CVE, is the standard system for identifying publicly disclosed cybersecurity flaws and is a key tool for companies assessing risk and prioritizing patches. Cybersecurity firm VulnCheck said increasingly capable AI-assisted tools are helping researchers uncover vulnerabilities that were previously difficult to detect. AI’s impact on vulnerability discovery has become even more apparent since Anthropic released a new model.
CVE disclosures by several software vendors have risen sharply in 2026, with Chrome’s count up 563.2% year on year. At the current pace, the full-year total could exceed 66,000. The Forum of Incident Response and Security Teams, or FIRST, has issued four recommendations, urging vendors and companies to strengthen their vulnerability prioritization, reporting and remediation capabilities.

The history behind this eventGoogle Uses AI to Fix 1,072 Chrome Security Bugs in June
Google’s Chrome security program has increasingly paired traditional code review and fuzzing with in-house artificial intelligence and large language models to uncover flaws that may have remained buried for years. The shift matters because Chrome is a gateway to online banking, commerce and corporate systems for billions of users, making faster vulnerability discovery and remediation a broad cybersecurity issue. Google said AI has materially changed the speed and scale of both detection and defense.
Google said on July 30 that Chrome 149 and Chrome 150, released to the stable channel on June 2 and June 30, 2026, respectively, fixed a combined 1,072 security bugs. That exceeded the 1,036 vulnerabilities repaired across the previous 23 Chrome milestones, compressing roughly two years of fixes into one month. The AI-assisted effort also uncovered a Chrome flaw that had remained undetected for 13 years, highlighting the technology’s growing role in finding long-lived weaknesses.
