Google Brotli Decoder Vulnerability CVE-2026-111497 Enables Remote Code Execution in Node.js, Python, Bun and Envoy

A critical out-of-bounds write flaw in Google's Brotli decoder (CVE-2026-111497) affects multiple widely used platforms including Node.js, Python, Bun and Envoy. Imperva researchers demonstrated reliable remote code execution on official Node.js 24.22.0 builds for Linux arm64, naming the exploit Node2Shell. The vulnerability allows crafted Brotli-compressed data to corrupt memory, leading to crashes, information leaks or arbitrary code execution. Affected versions include Node.js releases below 22.23.4, 24.22.1 and 26.12.1, plus all versions of the Python brotli and brotlicffi packages. Patches have been issued for Node.js, while other projects await updates; no in-the-wild exploitation has been observed yet. The incident highlights recurring supply-chain risks where a single foundational library impacts thousands of downstream applications.

Bot Traffic Overtakes Human Traffic in 2024 as AI Agents and Scrapers Surge

Analysis of internet traffic from 2013 to 2026 shows automated bots steadily eroding human dominance online. Imperva data reveals human traffic fell to 47 percent by 2025 while malicious bots reached 40 percent. Good bots such as search crawlers remain stable, but gray AI agents and scrapers now drive much of the growth. Companies face rising infrastructure costs from bot traffic that generates no revenue, described as an invisible tax. Cloudflare and Akamai reports confirm high volumes of automated requests, with many classified as harmful scraping. The trend raises concerns about a synthetic internet shaped more by AI recommendations than human activity.

WordPress Login Page Exposed to Critical XSS2Shell Flaw CVE-2026-64638: Over 11,000 Sites Attacked Across 67 Countries

WordPress core login page vulnerability CVE-2026-64638 enables unauthenticated attackers to trigger reflected XSS that can escalate to full server compromise. The flaw stems from mismatched HTML sanitization between two filtering layers on the wp-login.php page, allowing malicious payloads to execute in the site origin. Imperva observed automated campaigns hitting more than 11,000 sites with hundreds of thousands of requests, predominantly affecting U.S. targets in gaming, education, and finance sectors. Successful exploitation chains the XSS into WordPress REST API and application password creation when an administrator is logged in, ultimately allowing malicious plugin uploads. Official patches are available in WordPress 7.0.3 and backported releases down to 4.7; administrators are urged to verify versions, audit user accounts, and inspect plugin directories immediately.
