Fonts, CDNs, and Hosting: The Cross-Border Data Transfers No One Notices

A Russian developer building a contract-processing service discovered that his website was silently sending visitor data to foreign companies despite keeping all contract data on Russian servers. The site used Vercel for hosting, Google Fonts across 33 pages, and Cloudflare's cdnjs for PDF and Word libraries, exposing IP addresses, browsers, and browsing history. Under Russia's 152-FZ, such transfers require a separate notification to Roskomnadzor, and the United States and EU are not on the list of countries with adequate protection. The developer migrated fonts and libraries to his own Russian server, moved hosting domestically, and updated his privacy policy after a single console command revealed the external domains. The case highlights how common web practices like loading Google Fonts or using CDNs can trigger strict data localization and notification rules, with fines reaching millions of rubles for violations.

AWS and Vercel Patch Critical Flaws in AI Agent Platforms Allowing Unauthorized Tool Execution

AWS and Vercel have addressed multiple critical vulnerabilities in their AI agent platforms that enabled unauthorized execution of tools without legitimate model approval. The issues, grouped under the CoreBreak pattern, allowed attackers to bypass AI authorization checks by injecting crafted tool calls that the infrastructure misinterpreted as model-approved actions. In AWS, CVE-2026-18830 affected the InvokeHarness API in Amazon Bedrock AgentCore, permitting authenticated users to trigger sensitive tools directly. Vercel faced two separate flaws tracked as CVE-2026-64650 and CVE-2026-64651 that let sandboxed code reach host system tools, potentially exposing secrets or cloud APIs. No public evidence of active exploitation has been confirmed yet. Organizations are advised to apply updates immediately, restrict available tools for agents, and treat all external inputs as potentially malicious.
