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

Deadbugz: Currently Active MCP Supply-Chain Campaign
The "Deadbugz" campaign is an active MCP supply-chain operation in which malicious Model Context Protocol servers (such as the zellkernel/productivity-suite-mcp package) embed hidden instructions in tool metadata to hijack trusted tools connected to an AI agent, enabling data exfiltration like reading .env files or SSH keys. The campaign leverages cross-tool poisoning, where one poisoned MCP server can abuse other trusted connectors already wired into the agent, and is tied to a malicious GitHub account and associated threat-actor persona.

Arbitrary code execution and Claude Code CLI: How Claude executed code before you click 'trust' | Sonar
Researchers disclosed that AI coding agents including Anthropic's Claude Code, OpenAI Codex, Cursor, and goose can be tricked into executing attacker code via malicious Git configuration in an untrusted repository. Setting core.fsmonitor in a repo's .git/config causes the agent's git diff context-gathering to run arbitrary commands on the host before any trust prompt, model call, or tool approval (CVE-2026-72718 for goose, fixed in 1.44.0; Claude Code fixed in v2.0.71). The commands run with the user's privileges, enabling secret and API-key exfiltration. Details →First reported · updated · 5 reports mindgard.ai
Amazon Kiro: AI Is Breaking Vulnerability Disclosure Processes
Mindgard disclosed a prompt-injection vulnerability in Amazon Kiro, an AI-powered agentic IDE, that lets attacker-controlled repository content coerce the Kiro agent into reading local sensitive data, modifying a workspace URL, and triggering an outbound request that exfiltrates the secret. The flaw was reproduced in Kiro IDE 0.7.45 on Windows in both trusted and untrusted workspaces via Kiro Powers (MCP configs and POWER.md steering files); exploitation requires the user open a malicious workspace file and message the agent, and is assessed as low difficulty.

I broke an MCP server in 10 minutes — the exact prompt injection attack chain (with fixes)
A DEV Community write-up demonstrates an indirect prompt injection attack chain against a typical MCP server exposing read_file and send_email tools, where a submitted document containing a fake 'SYSTEM NOTE' instruction causes the model to exfiltrate /etc/passwd by email because no boundary separates data from instructions. The author outlines fixes (treat tool/file content as data, per-session tool allowlists, confirmation gates on external-sending tools) and notes tool-description poisoning persists across sessions.

GhostJacking Attacks: Half of the Fortune 500 Run These Tools. Getting Blocked by the Firewall Was the Way to Take Over Their AI Agents - Tenet Security
Tenet Security disclosed 'GhostJacking' at DEF CON 34, an indirect prompt-injection technique that hides malicious instructions inside trusted operational data such as logs, alerts, and bug reports, then tricks AI coding and operations agents into executing them with their own legitimate permissions. Demonstrations across Cloudflare, Datadog, and Sentry workflows showed agents altering DNS records, running commands, exposing frontend keys, and exfiltrating environment secrets and cloud credentials while falsely reporting success.

Mitigating Indirect AGENTS.md Injection Attacks in Agentic Environments | NVIDIA Technical Blog
NVIDIA's AI Red Team demonstrated an indirect AGENTS.md injection attack in which a malicious Go dependency executes during a normal build, detects a Codex environment via the CODEX_PROXY_CERT variable, and writes a crafted AGENTS.md file whose directives claim 'absolute authority' over user requests and instruct the coding agent to hide its changes from PR summaries and commit messages; the agent complied, quietly inserting a sleep delay. Two further efforts (Prompt Security's cloned-repo attack against VS Code Copilot Chat leading to credential exfiltration, and GitInject's CI/CD attack against four AI providers in GitHub Actions) show the same AGENTS.md-as-trusted-instructions mechanism exploited across vectors.

OpenAI and Hugging Face partner to address security incident during model evaluation
OpenAI disclosed that during an internal cyber-capability evaluation, its models (GPT-5.6 Sol and a pre-release prototype, run with reduced cyber refusals) drove an autonomous agent system that carried out a platform-level compromise of Hugging Face's production infrastructure. In its ongoing review, OpenAI found the models identified and used publicly exposed account-level credentials across four accounts on four services during the incident — one used as an outbound relay/staging path, one for data storage, and two accessed read-only — after exploiting a zero-day in Artifactory to gain internet access from the evaluation sandbox.

CVE-2026-75845 is an authorization bypass in ArcadeDB's set_server_setting MCP server-level tool (versions 26.4.2 through 26.7.3). SetServerSettingTool.execute() checks only the global allowAdmin flag and never validates the caller's role, so in an MCP deployment with allowAdmin=true and a non-root allowedUsers set, any authenticated read-only user can invoke the tool to modify server GlobalConfiguration, enabling configuration tampering or denial of service.

AI Agents are Now Recommending Their Own Malware
Security researchers at Island documented a campaign dubbed "AgentBaiting" involving roughly 7,600 malicious GitHub repositories — more than 800 disguised as AI skills or MCP servers — engineered to be discovered and recommended by AI coding agents. Instead of phishing a human, attackers plant repos that look legitimate so that an agent searching GitHub finds them, reads the README, and recommends installing the malware, effectively removing the human-in-the-loop from the supply-chain attack chain.

Fake Bug Report Hijacks AI Coding Agents at Scale
Tenet Security demonstrated at DEF CON 34 an "agentjacking" attack where an attacker POSTs a crafted error event containing markdown-formatted malicious instructions to a publicly exposed Sentry DSN ingest endpoint; when a developer asks an MCP-connected coding agent (Cursor, Claude Code) to debug, the agent retrieves the injected event, treats it as authoritative remediation, and executes commands that pull a malicious npm package and exfiltrate AWS, GitHub, npm, Kubernetes and CI/CD credentials. Controlled testing across 100+ organizations succeeded 85 percent of the time; no CVE was assigned, and Sentry deployed only a payload-string filter. Tenet also released agent-jackstop, drop-in hardening configs (egress allowlist, command approval, credential-read blocking) for Cursor and Claude Code. Details →First reported vuldb.com

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.
