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

SVD-2026-0808 | Splunk Vulnerability Disclosure
Splunk advisory SVD-2026-0808 discloses multiple vulnerabilities in Splunk apps including a critical (CVSS 9.1) remote code execution via untrusted-data deserialization (CVE-2026-76404) in the Splunk MCP Server app, plus several flaws in the Splunk AI Toolkit such as RCE in the Model Loading REST API (CVE-2026-76395), improper privilege management on agent run history (CVE-2026-76391), and missing authorization in container/connection management (CVE-2026-76394). Fixed versions are available for each affected app and add-on. Details →First reported · updated · 2 reports cve.org
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 sentry.security
Beyond Prompt Injection: Hacking Apple's Private Cloud Compute
Security researcher Drinor found CVE-2026-20685, a path traversal in darwin-init (the PID 1 root provisioning process) of Apple's Private Cloud Compute, the server-side inference backbone of Apple Intelligence. The flaw lets an attacker write files as root during boot and redirect a node's inference telemetry to an attacker-controlled server, breaking PCC's stateless, attested, and sealed-observability privacy guarantees. Apple assigned the CVE and awarded a $150,000 bounty; the researcher found it via Apple's Virtual Research Environment. Details →First reported redhat.com
CVE-2026-12112 - Red Hat Customer Portal
CVE-2026-12112 is a session management flaw in the foreman-mcp-server (MCP Server) shipped with Red Hat Satellite 6.18 and 6.19, where unauthenticated attackers can hijack active administrative sessions because the server caches authenticated client connections and trusts a non-secret session ID without re-validating authentication tokens, while also logging newly created session IDs to standard logs. Rated 7.8 CVSS v3 (Important), it can lead to privilege escalation and infrastructure-wide code execution; Red Hat has issued fixes via RHSA-2026:28405 and RHSA-2026:28438.

Claude Cowork Flaw Could Let AI Agent Escape Its VM and Access Mac Files
Researchers at Accomplish AI disclosed SharedRoot (CVE-2026-46331), a sandbox escape vulnerability in Anthropic's Claude Cowork that lets the AI agent break out of its Linux VM and read or write arbitrary files on the host Mac. A single message to a fresh session let the agent reach files far outside the connected folder with no permission prompt, exposing SSH keys, cloud credentials, and other data; roughly 500,000 macOS users were affected before Anthropic patched it.

AI Agents Project Viewer Privilege Escalation via run_node_tool · Advisory · n8n-io/n8n
A GitHub Security Advisory (GHSA-x5vx-c2c8-m3w9) for n8n discloses a privilege-escalation flaw in its AI Agents feature: a read-only Project Viewer could chat with an agent whose node tools were enabled and, via the run_node_tool authorized only by the agent:execute scope, execute arbitrary tool nodes using the project's credentials without authorization checks. Where command- or file-capable nodes (Execute Command, SSH) are enabled, this could extend to arbitrary command execution on the n8n host. The issue is fixed in n8n versions 2.29.8 and 2.30.1.

A Security Analysis of the OpenClaw AI Agent Framework
Researchers detailed three now-patched high-severity flaws (GHSA-hjr6-g723-hmfm, GHSA-9969-8g9h-rxwm, GHSA-575v-8hfq-m3mc; CVE-2026-46817, CVE-2026-55200) in the OpenClaw personal AI assistant framework that compose into a complete unauthenticated remote code execution path — from an LLM tool call triggered via a WhatsApp message to command execution on the host. The chain abuses OS command injection and an incomplete disallowed-input filter in the exec allowlist, whose closed-world lexical parsing is defeated by shell line continuation, busybox multiplexing, and GNU option abbreviation; a companion arXiv analysis taxonomizes 470 advisories and shows a malicious plugin skill bypassing the exec pipeline entirely.
