A disclosed Cursor vulnerability let an attacker poison the agent's execution environment so an allowlisted command delivered an arbitrary payload. The allowlist made the attack easier, because it auto-approved exactly the command the attacker needed. (Lushbinary) Command allowlists are not a sandbox. OWASP's State of Agentic AI Security v2.01 catalogs this alongside CVE-2026-2256, a command-injection flaw in ModelScope's MS-Agent shell tool. Audit your "safe command" list for anything an attacker could repurpose, and run the agent in a real jail.

Go look at your ~/.claude/CLAUDE.md right now. Mine has internal package names, a build command with a host in it, and notes about which credentials live where. I wrote it assuming exactly one reader. RuntimeWire published traced request captures on August 9 showing Muse Code...
This is the highest-conviction story in today's set, because four independent sources landed on the same conclusion in the same window. The consensus: prompt injection isn't a patchable bug. It's inherent to how LLMs work. (Tech Times) The mechanism is simple and that's exactl...
Of 53 tracked agentic projects, 28 are coding agents, and the five fastest-growing tools, Claude Code, Gemini CLI, Codex, Cline, and Aider, are all in that category (Help Net Security). Security advisories cluster around n8n (57), Claude Code (22), AutoGPT (15), Dify (13), and...
Microsoft researchers detailed SymJack, a symlink-hijack RCE affecting six coding agents, and TrustFall, which impacts Claude Code, Cursor, Gemini CLI, and GitHub Copilot (Microsoft Security). These join Semantic Kernel prompt-injection-to-host-RCE flaws. The local coding agen...
The trick is one line in a file you never read. Manifold Security published eight findings across seven coding agents (Claude Code, Codex, Cursor, Grok Build, Qwen Code, goose, Hermes Agent) that all reduce to the same mechanism. A repository's own .git/config sets core.fsmoni...
A GitHub repo cataloging Claude Code tips doesn't normally warrant a top story. But shanraisshan/claude-code-best-practice at 53.4K stars isn't a tips list anymore. It's the de facto reference for how an entire generation of developers is learning to work with AI coding agents...
