Brotli RCE Flaw Demands Immediate Patching of Affected Release Lines","A memory corruption vulnerability in Node.js's Brotli decompression library (CVE-2026-111497) allows attackers to achieve remote code execution simply by sending maliciously crafted compressed data to an affected application. This is particularly dangerous because Brotli decompression is a common, often implicit operation in web-facing Node.js services, meaning the attack surface is broad and exploitation requires no authentication. Fixes are available across all affected release lines (22.x, 24.x, 26.x), making delayed patching the primary risk factor.
