53 OpenJDK Vulnerabilities Disclosed Today Set an All-Time High; Azul Patches Them All
Azul's Security-only, Stability-first™ updates can be deployed immediately to counter the speed of agentic AI threats
SUNNYVALE, Calif., October 20, 2026--Azul, the trusted leader in enterprise Java for today's AI-first world, today released its October Security-only, Stability-first™ updates for Azul Core that are immediately deployable to address all 53 vulnerabilities disclosed in the latest OpenJDK quarterly update. Azul's Security-only, Stability-first updates contain security fixes and nothing else: no new features, enhancements or unrelated changes that can cause problems. The number of vulnerabilities disclosed in this quarter's OpenJDK release is the most in a single update in well over a decade and 7x greater than the two-year average of 7.6 Common Vulnerabilities and Exposures (CVEs) per quarter.
OpenJDK quarterly updates that include the fixes to these CVEs also include more than 150 code changes unrelated to security. Azul is the only vendor to offer both monthly and quarterly updates scoped to just security fixes. Enterprises can deploy Azul's Security-only, Stability-first updates to production immediately and safely to remediate critical vulnerabilities. Other OpenJDK distributions bundle non-security bug fixes, enhancements and even features in their updates, often causing regressions. While such regressions may get fixed with follow-on updates, they can significantly delay the deployment of urgent security fixes.
AI Is Exposing Flaws and Enabling Exploits Faster than Ever
CSO recently reported that researchers using an AI tool found a 13-year-old remote code execution flaw in Apache ActiveMQ in about 10 minutes. Two weeks after disclosure, nearly 6,500 internet-facing instances were still unpatched. In a case documented by GreyNoise, a suspected attacker used hundreds of AI agents to chain two zero-day flaws in PaperCut NG/MF, going from an empty workspace to remote code execution in under four hours. The agents ultimately reached at least 440 instances across 395 organizations in 48 countries, with full domain administrator control in seven minutes.
Java has been running mission-critical systems for more than 30 years, making it one of the most battle-tested platforms in enterprise computing. But AI is now exposing flaws that survived years of testing and review. Researchers are using it to uncover vulnerabilities in decades-old code, while threat actors use agentic AI to find and exploit them at a speed and scale never seen before. Because the vast majority of enterprises rely on Java for production applications and infrastructure, the impact will be felt in every industry and region. And the risk is immediate, for three reasons:
