AWS Kiro: Arbitrary Code Execution via Indirect Prompt Injection
Researchers found a vulnerability (CVE-2026-10591) in AWS Kiro, an agentic IDE, where hidden instructions planted in a web page or source file that Kiro processes can trigger indirect prompt injection to rewrite Kiro's own MCP server configuration (~/.kiro/settings/mcp.json) or allowlist arbitrary Bash commands in .vscode/settings.json, achieving arbitrary code execution on the developer's machine with no approval prompt. The human-in-the-loop approval boundary is bypassed because Kiro can write to these config files without user consent, and AWS has issued a fix and CVE.indirect-prompt-injection · prompt-injection · remote-code-execution · tool-abuse · config-poisoning

Path to Astra: critical capabilities and frontier safeguards
OpenAI announced that its model 'Astra' (GPT-6) meets the 'Critical' cybersecurity capability threshold under its Preparedness Framework, meaning that with the right tools and access it can autonomously find previously unknown flaws and develop exploits across many hardened systems without step-by-step human guidance. The company describes strengthened safeguards, delayed release, misuse monitoring, and limited initial access to the model's most advanced cyber capabilities, referencing evaluations such as ExploitBench and an internal V8-vulnerability benchmark.

Grok chat history leak: Cryptographic Context Injection
Adversa AI disclosed a new technique it calls Cryptographic Context Injection, which hides malicious instructions inside AES-256-GCM ciphertext so static guardrails cannot read them, then induces the model to decrypt them in its own code-execution sandbox where the recovered plaintext is treated as trusted instructions. Against xAI's Grok web chat, a benign 'summarize this page' request triggers zero-click exfiltration of the user's session data and chat history to an attacker URL; against Gemini it produces content the model normally refuses. Reported to xAI in June 2026 and still reproducible as of August 19, while Gemini's success rate has fallen but is not fully closed. Details →First reported · updated · 4 reports sonarsource.com
Arbitrary code execution and Claude Code CLI: How Claude executed code before you click 'trust' | Sonar
Malicious .git/config files can trigger arbitrary code execution in AI coding agents before any trust prompt or model call. Sonar researchers found Claude Code CLI could be compromised (patched in v2.0.71 / Dec 16, 2025) by cloning an untrusted repo, and CVE-2026-72718 shows the goose AI agent's 'goose review' command runs git with attacker-controlled config (core.fsmonitor), executing commands during 'git diff HEAD' — fixed in goose 1.44.0.

MCP's Broken Trust Model: Tool Poisoning, Rug Pulls, and the New Threat Landscape

ASCII smuggling crosses over from AI prompt injection to phishing evasion | Microsoft Security Blog
Microsoft reports that ASCII smuggling — hiding content in invisible Unicode tag characters, a technique popular for indirect prompt injection against AI models — has been repurposed by phishers to split financial-lure keywords (e.g. "fun[U+E0020]ding") and evade content filters in a campaign that peaked above 2.37 million messages in late February. Analysis found no smuggled AI instructions in the flagged messages; the invisible characters were used purely for keyword-filter evasion, illustrating how AI-era attack methods cross over into traditional threats.

AI Jailbreak Prompts Are Evolving Into Real Cyber Threats
Bitsight Threat Intelligence research covering July 2025 through July 2026 tracked jailbreak activity across forums, GitHub repositories, Telegram channels, and marketplace conversations, finding that threat actors are moving beyond static jailbreak prompts toward obfuscation, model routing, retry logic, multi-model testing, and repeatable jailbreak workflows.

Insurers Search for Answers to Rein in Rogue AI
Hugging Face disclosed a July 2026 intrusion into its production infrastructure driven end-to-end by an autonomous AI agent framework, which abused two code-execution paths in its dataset-processing pipeline (a remote-code dataset loader and a template-injection in a dataset config) to run code on a worker, then escalated to node-level access, harvested cloud and cluster credentials, and moved laterally across internal clusters using swarms of short-lived sandboxes and self-migrating C2.

Malicious LiteLLM Releases Tied to Trivy Hack May Have Exposed 2,100+ Organizations
TeamPCP compromised the GitHub Actions pipeline of the Trivy scanner used in LiteLLM's CI/CD, stole LiteLLM's PyPI publishing tokens, and published malicious LiteLLM packages (versions 1.82.7 and 1.82.8) whose .pth startup-hook payload harvested AI provider credentials, cloud keys, and CI/CD secrets, attempted Kubernetes lateral movement, and installed a systemd backdoor.
