Threat Intelligence Brief
Curated summary with source attribution
Source: thehackernews.com
Threat Risk: High
Victim: Applications utilizing Node.js 22.x, 24.x, or 26.x
Incident: A remote code execution vulnerability (CVE-2026-111497) was identified in the Node.js Brotli decoder.
Impact: Successful exploitation allows for full system compromise via arbitrary code execution.
Attacker: Unidentified threat actors
Analysis: The Node2Shell exploit targets a memory corruption vulnerability in the Brotli decoder bundled with Node.js. By feeding crafted data through HTTP requests or responses, an attacker can trigger an out-of-bounds write leading to remote code execution. Although no wild exploitation is reported, a successful PoC confirms the risk on standard Linux arm64 builds.
Recommendations: Update Node.js to the latest patched versions, such as 24.22.1.; Audit container images and bundled binaries to ensure they are not using outdated Node runtimes.; Deploy WAF rules to filter or limit untrusted Brotli-compressed traffic on affected paths.
