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

NVD - CVE-2026-62676
CVE-2026-62676 is a HIGH-severity (CVSS 7.1) flaw in Omnigent, an open-source AI agent framework and meta-harness for orchestrating coding agents. Prior to 0.3.0, the shared shell-command parser in _shell.py fails to recognize combined interpreter flags, timeout/nice/setsid/stdbuf wrappers, command substitutions, and a background control operator, so a gated git push or gh write hidden in these forms produces no parsed operation, causing the repo/branch allowlist and workspace confinement policies to abstain and allow the command. An authenticated or prompt-injected agent can push to an unauthorized repository or branch or escape the intended workspace; fixed in version 0.3.0.

CVE Record: CVE-2026-75845
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. The issue is fixed in 26.8.1. Details →First reported feedly.com

AWS, Google, and Vercel Agent Flaws Let Attackers Trigger Tools Without Running the Model
Security flaws in agent infrastructure from AWS (Bedrock AgentCore's InvokeHarness API), Google (Agent Development Kit for Python), and Vercel (AI SDK harness packages for Codex and OpenCode) allow untrusted or forged instructions to reach an agent's tools without verifying that a model turn authorized them. In several attack paths the model never ran, so system prompts, content filters, and model-level guardrails never engaged. AWS fixed the managed service, Google addressed the issues in ADK 2.5.0, and Vercel patched @ai-sdk/harness-codex 1.0.29 and @ai-sdk/harness-opencode 1.0.28. Details →First reported oasis.security
