Think your Wi-Fi is safe? Your coding tools? Or even your favorite financial apps? This week proves again how hackers, companies, and governments are all locked in a nonstop race to outsmart each other. Here’s a quick rundown of the latest cyber stories that show how fast the game keeps changing. DeFi exploit drains funds Critical yETH Exploit Used to Steal $9M

As 2025 draws to a close, security professionals face a sobering realization: the traditional playbook for web security has become dangerously obsolete. AI-powered attacks, evolving injection techniques, and supply chain compromises affecting hundreds of thousands of websites forced a fundamental rethink of defensive strategies. Here are the five threats that reshaped web security this year, and

### Impact There is an unauthenticated remote code execution vulnerability in React Server Components. We recommend upgrading immediately.

If you are using any of the above packages please upgrade to any of the fixed versions immediately. If your app’s React code does not use a server, your app is not affected by this vulnerability. If your app does not use a framework, bundler, or bundler pl...

A maximum-severity security flaw has been disclosed in React Server Components (RSC) that, if successfully exploited, could result in remote code execution. The vulnerability, tracked as CVE-2025-55182, carries a CVSS score of 10.0. It allows "unauthenticated remote code execution by exploiting a flaw in how React decodes payloads sent to React Server Function endpoints," the React Team said in

Due to errors in parsing shell commands related to $IFS and short CLI flags, it was possible to bypass the Claude Code read-only validation and trigger arbitrary code execution. Reliably exploiting this requires the ability to add untrusted content into a Claude Code context window. Users on standard Claude Code auto-update have received this fix already. Users performing manual updates are advised to update to the latest version. Thank you to [RyotaK](hxxps://ryotak.net) from [GMO Flatt Security Inc.](hxxps://flatt.tech/en/) for reporting this issue!

The Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default for HTTP-based servers. When an HTTP-based MCP server is run on localhost without authentication with `StreamableHTTPServerTransport` or `SSEServerTransport` and has not enabled `enableDnsRebindingProtection`, a malicious website could exploit DNS rebinding to bypass same-origin policy restrictions and send requests to the local MCP server. This could allow an attacker to invoke tools or access resources exposed by the MCP server on behalf of the user in those limited circumstances. Note that running HTTP-based MCP servers locally without authentication is not recommended per MCP security best practices. This issue does not affect servers using stdio transport. Servers created via `createMcpExpressApp()` now have this protection enabled by default when binding to localhost. Users with custom Express configurations are advised to update to version `1.24.0` and apply the exported `hostHe...

North Korean hackers escalated the "Contagious Interview" attack, flooding the npm registry with over 200 malicious packages to install OtterCookie malware. This attack targets blockchain and Web3 developers through fake job interviews and coding tests.

The supply chain campaign known as GlassWorm has once again reared its head, infiltrating both Microsoft Visual Studio Marketplace and Open VSX with 24 extensions impersonating popular developer tools and frameworks like Flutter, React, Tailwind, Vim, and Vue. GlassWorm was first documented in October 2025, detailing its use of the Solana blockchain for command-and-control (C2) and harvest npm,

Cybersecurity researchers have disclosed details of an npm package that attempts to influence artificial intelligence (AI)-driven security scanners. The package in question is eslint-plugin-unicorn-ts-2, which masquerades as a TypeScript extension of the popular ESLint plugin. It was uploaded to the registry by a user named "hamburgerisland" in February 2024. The package has been downloaded

North Korean attackers have delivered more than 197 malicious packages with 31K-plus downloads since Oct. 10, as part of ongoing state-sponsored activity to compromise software developers.
