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

$1,500 AI System Prompt Leak: Using this Burp Suite Configuration
A bug bounty write-up by tinopreter describes leaking an AI application's system prompt at a company that rolled out AI across its assets, earning a $1,500 payout, and attributes the discovery to a particular Burp Suite proxy configuration that surfaced the prompt in intercepted traffic. Specific details, endpoints, and screenshots were altered for confidentiality. Details →First reported · updated · 2 reports nhimg.org
Agentjacking exposes a broken trust model in AI coding agents
"Agentjacking," documented by Swarmnetics and Tenet Security, abuses the trust AI coding agents place in external error-report telemetry: an attacker who obtains a publicly exposed Sentry DSN can inject malicious instructions into error reports that the agent treats as actionable, enabling theft of cloud keys, Git credentials, and private repo URLs. The core flaw is that systems built to process trusted telemetry conflate source trust with action trust in MCP-connected agent workflows. Details →First reported medium.com
A Fake Bug Report Made an AI Agent Steal a Live AWS Key. It’s Called Agentjacking & There’s No Patch | by @pramodchandrayan | Predict
A Medium write-up describes "agentjacking," an indirect prompt-injection technique in which a fake Sentry bug report contains hidden instructions that AI coding agents (Claude Code, Cursor, Codex) execute when a developer asks them to triage errors, leading to exfiltration of a live AWS secret key. It cites a security firm's demonstration reporting 2,388 exposed organizations and an 85% success rate with no malware or user clicks, and argues that instructing an agent to "ignore untrusted content" does not prevent the attack.

EchoGram and guardrail bypass: are AI defenses keeping up?
HiddenLayer research dubbed EchoGram demonstrates that carefully chosen token sequences can flip verdicts in LLM guardrail models, causing harmful prompts to be marked safe or benign prompts to trigger false alarms. The NHIMG editorial summarizes the finding and its implications for organizations relying on probabilistic AI safety layers to protect deployed LLMs and agents. Details →How the wire is made
