How to Audit and Harden Claude Code CLI Against CVE-2026-35020, 35021, and 35022

Three command injection vulnerabilities in Claude Code CLI — CVE-2026-35020, CVE-2026-35021, and CVE-2026-35022 — carry CVSS scores of 9.8 (Critical) and chain together to enable credential exfiltration over HTTP. If you’re running Claude Code in any CI/CD pipeline, this guide walks you through immediate mitigation steps and longer-term hardening practices. This is not optional maintenance. These are exploitable, validated vulnerabilities with confirmed callback evidence. Prerequisites Access to your Claude Code CLI deployment(s) Access to your CI/CD pipeline configurations (GitHub Actions, GitLab CI, Jenkins, or equivalent) Basic shell access to environments where Claude Code runs Permission to update environment variable configurations and outbound network rules Step 1: Check Your Version and Patch Immediately The vulnerabilities are confirmed exploitable on v2.1.91 and earlier. Your first action is to identify and update every Claude Code CLI instance. ...

Microsoft Agent Framework 1.0 Officially Ships — Stable APIs for .NET and Python, LTS Commitment

It’s been a long road from “interesting prototype” to “production-ready.” As of April 3, 2026, Microsoft Agent Framework has officially reached version 1.0 — and with it comes a long-term support commitment, stable APIs for both .NET and Python, and a clear answer to the question developers have been asking for a year: is this thing safe to build on? The answer is now yes. What Ships in 1.0 Agent Framework 1.0 brings together several threads that Microsoft has been developing in parallel. The framework unifies the enterprise-ready foundations of Semantic Kernel with the orchestration capabilities of AutoGen into a single, open-source SDK. That consolidation has been the core promise since the project launched last October — and 1.0 is the first release that fully delivers on it. ...

Three Critical CVEs in Claude Code CLI Chain to Credential Exfiltration — Bypass Patch Also Shipped April 6

If you’re running Claude Code CLI in any CI/CD pipeline, stop what you’re doing and check your version. Right now. Three newly registered CVEs — CVE-2026-35020, CVE-2026-35021, and CVE-2026-35022 — are command injection flaws in Claude Code CLI that researchers at phoenix.security validated as exploitable on v2.1.91 as recently as April 3, 2026. They chain together to enable credential exfiltration over plain HTTP, and every one of them carries a CVSS score of 9.8 (Critical). On top of that, Anthropic shipped a separate patch on April 6 for a distinct high-severity deny-rule bypass — both security issues trace back to the same Claude Code source leak. ...

Multi-Agent Is the New Microservices — And Enterprises Are Already Making the Same Mistakes

Somewhere in your company’s recent strategy deck, there’s a slide about multi-agent AI systems. It probably has a diagram with six or eight boxes connected by arrows, each box representing a specialized agent — one for research, one for synthesis, one for outreach, one for quality control. It looks clean. It looks powerful. It looks exactly like the microservices architecture slides that were circulating in 2014. InfoWorld is issuing the same warning now that engineers were quietly issuing then: distributed complexity is not a free upgrade. You have to earn it. ...

Claude Code Ultraplan: Offload Your Hardest Planning Tasks to the Cloud While You Keep Coding

Planning is often the hardest part of a complex engineering task — and it’s exactly the kind of work that benefits from more thinking time, more model capacity, and fewer interruptions. Claude Code’s new Ultraplan feature addresses all three. What Ultraplan Does Ultraplan is a new Claude Code feature that offloads planning tasks to a remote Cloud Container Runtime (CCR) running Opus 4.6 in plan mode for up to 30 minutes. While the remote planning session runs, you continue working locally — no waiting, no blocking, no half-finished thought processes. ...

The One-Person Billion-Dollar Startup Is Here — OpenClaw, Base44, and Daymaker Prove It

Sam Altman predicted it. He said AI would enable “one-person billion-dollar companies.” For most of 2024, that was a provocative thought experiment. In April 2026, it’s a Forbes article with case studies. The Three Companies Forbes Profiles Medvi is the headline data point. A telehealth company valued at $1.8 billion. Built in 14 months. Staff at time of valuation: 2 people. Total startup capital: $20,000. That last number deserves a full stop. Twenty thousand dollars. The kind of money that, five years ago, wouldn’t have lasted six months in a San Francisco office before running out on rent and coffee. ...

Privileged Access Management Is Becoming the Real-Time Control Plane for AI Agents

Traditional Privileged Access Management was built around a simple premise: human users need elevated access sometimes, so we vault those credentials, require checkout, and log who used what when. It works reasonably well for humans, who operate on human timescales, request access explicitly, and can be held accountable by name. AI agents operate differently. They access dozens of systems in parallel, at machine speed, for tasks that were authorized in general but not pre-approved in each specific instance. The traditional PAM model — vault credentials, check them out, check them back in — doesn’t map cleanly onto an agent that makes 200 API calls in thirty seconds across five different systems. ...

Anthropic Tests 'Conway' — A Persistent Always-On Agent Platform to Rival OpenClaw

The race to own the persistent AI agent layer just got a lot more interesting. Anthropic is testing Conway, an internal platform that transforms Claude into an always-on, autonomous environment — and the company’s Chief Commercial Officer has all but confirmed they’re building a direct OpenClaw competitor. What Is Conway? Conway is Anthropic’s answer to the question their customers keep asking: why do I need a third-party tool to run Claude autonomously? ...

Highflame and Tailscale Partner to Secure AI Agents and MCP Interactions at the Network Layer

On the same day that two critical OpenClaw vulnerabilities are making headlines, a partnership announcement hits the timing perfectly: Highflame and Tailscale have announced an integration that brings real-time security evaluation to AI agent and MCP (Model Context Protocol) interactions — at the network layer, without requiring code changes. The timing is almost too on the nose. But the underlying problem this partnership addresses is real and growing. The Problem: Agentic AI’s Security Gap Modern AI agent frameworks — OpenClaw, MCP-based systems, enterprise Copilot deployments — generate a constant stream of interactions between language models, tools, APIs, and external services. Each of those interactions is a potential attack vector. ...
