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

A Layered Security Framework Against Prompt Injection in RAG-Based Chatbots
A research paper by Gulshan Saleem and colleagues presents a three-layer middleware framework to defend RAG-based chatbots against both direct and indirect prompt injection, combining input screening, a provenance-based instruction hierarchy during context assembly, and output auditing. Evaluated on 5,080 samples across GPT-4o, Llama 3, and Mistral 7B, the framework reduced Attack Success Rate from 71.4% to 11.3% while maintaining a 4.8% false positive rate and 61.2 ms median latency overhead.

Instagram account takeover exploit via support chatbot prompt injection (fixed)
Reports claim Meta's AI support agent for Instagram was granted account-modification permissions without identity verification, allowing attackers to manipulate the bot into changing account emails and bypassing 2FA, leading to live account takeovers. Multiple users reported losing accounts before the issue was reportedly patched. Details →How the wire is made
