According to a recent LinkedIn post from HeroDevs, the company is drawing attention to multiple security vulnerabilities disclosed in the June 2026 Node.js release, including 12 CVEs, two rated High. The post notes that 10 of these issues affect end-of-life Node 18 and 20, versions that still saw more than 135 million downloads in June despite no upstream patches.
The company’s LinkedIn post highlights a pattern of TLS and mTLS trust failures linked to hostname handling, such as Unicode dot separators, embedded NUL bytes, uppercase SNI mismatches, and unsafe session reuse across server names. The post suggests HeroDevs positions its NES offering as a way to maintain security coverage for end-of-life Node versions, indicating potential recurring revenue opportunities from organizations running legacy Node deployments.
From an investor perspective, the emphasis on unpatched but heavily used Node versions underscores a sizable addressable market for extended support and security services. This focus on high-severity CVEs may strengthen HeroDevs’ value proposition within open-source security and enterprise infrastructure, potentially supporting customer acquisition among risk-sensitive users and enhancing the firm’s competitive standing in the Node.js ecosystem.
