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

CoSnitch: When Your AI Assistant Becomes Its Own Whistleblower
Varonis Threat Labs disclosed CoSnitch (CVE-2026-24301), a critical one-click vulnerability chain in Microsoft Copilot Personal that combines the ?q= URL parameter with an undocumented autorun=1 parameter to auto-execute an attacker-supplied prompt on page load, then queries connected apps (Gmail, Drive, Calendar, OneDrive) and exfiltrates data via encoded URLs, plus indirect prompt injection through web summarization that poisons persistent memory. Researchers used a 'meta-hacking' technique, repeatedly asking Copilot why an attack wouldn't work until the assistant disclosed its own disabled parameters and session conditions. Microsoft shipped patches on August 18, 2026; Varonis reports no evidence of in-the-wild exploitation. Details →First reported · updated · 5 reports bugcrowd.com
Atlassian Rovo Can Be Tricked Into Sending Jira and Confluence Data to Attackers
Researchers at Varonis Threat Labs (RovoBlast) and PromptArmor independently showed that Atlassian's Rovo AI assistant can be manipulated via prompt injection to collect Jira and Confluence data a signed-in user can access and exfiltrate it to an external server. Varonis found that the rovoChatPrompt URL parameter preloads attacker instructions so a single click by an authenticated user triggers execution; PromptArmor hid instructions in an uploaded file that Rovo reads, working even with web-search disabled. Varonis's route was responsibly disclosed and fixed (CVE-2026-50522), while the PromptArmor file-based bypass is single-sourced and its remediation is not confirmed.

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.

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.

From SQLi to RCE - Exploiting LangGraph’s Checkpointer - Check Point Research
Check Point Research (Yarden Porat and Shahar Tal) disclosed 11 vulnerabilities across six major AI agent frameworks — LangChain, LangGraph, CrewAI, AutoGen, the Microsoft Agent Framework, and Google ADK — including insecure deserialization, SSRF, path traversal, SQL injection, and use-after-free flaws. The most severe were RCE chains: a checkpoint deserialization flaw in the Microsoft Agent Framework triggerable via prompt injection, unauthenticated code execution in Google ADK, and three LangGraph checkpointer bugs (CVE-2025-67644, CVE-2026-28277, CVE-2026-27022). All disclosed issues were patched. Details →First reported · updated · 3 reports pillar.security
ChainDrop: When Opening a Repository Becomes Execution
Researchers (Novee Security and Pillar Security's "ChainDrop") disclosed critical flaws in the GitHub Actions-based coding agents shipped by Anthropic (Claude Code), Google (Gemini CLI) and OpenAI (Codex), where a single zero-privilege input such as a GitHub issue or opening a repository triggers indirect prompt injection leading to remote code execution on the vendor's own runner, exfiltration of live API keys and GITHUB_TOKEN, persistent agent hijacking, and downstream supply-chain compromise (Gemini CLI rated CVSS 10.0). Multiple CVEs (e.g. CVE-2026-54316, CVE-2026-12537, CVE-2026-50522) and vendor security advisories were issued, but the report warns thousands of public repos running default configs remain exposed.

NVD - CVE-2026-70477
CVE-2026-70477 is a critical (CVSS 9.5) vulnerability in Flowise prior to 3.1.3, where a prompt injection sent to a chatflow using the CSV Agent node can cause the LLM to emit malicious Python that bypasses the blocklist validator (validatePythonCodeForDataFrame) and executes in an unsandboxed Pyodide environment. The flaw in the CSV_Agents class run method lets an attacker achieve arbitrary code execution in the context of the service account; it is fixed in version 3.1.3. Details →First reported nhimg.org
Copilot vulnerability turns AI assistance into a data theft force
A Copilot Enterprise vulnerability chain, detailed by Swarmnetics and Varonis Threat Labs, showed how prompt injection combined with browser handling quirks and whitelisted endpoints can let an attacker move from a link click to rapid theft of emails, files, and meeting data across a Microsoft environment. The core issue is a broken trust boundary between a query, a link, and the content the assistant is allowed to surface, letting attacker-shaped input ride through the assistant's trusted context.

DuneSlide: Two Critical RCE vulnerabilities
Cato AI Labs disclosed two critical remote code execution flaws in the Cursor AI code editor, collectively named DuneSlide (CVE-2026-50548 and CVE-2026-50549, both CVSS 9.8), that let a zero-click prompt injection break out of the editor's terminal sandbox by overwriting critical system files like the cursorsandbox binary, converting sandboxed agent commands into unsandboxed RCE. The flaws affect all versions before Cursor 3.0 and are patched in Cursor 3.0, released April 2. Details →First reported mallory.ai
Researchers Expose Prompt Injection and Cross-Origin Risks in AI Browsers
Researchers and vendors disclosed serious weaknesses in AI-enabled browsers, warning that agentic features undermine same-origin policy, tab isolation, and cross-origin content handling. In one chain against OpenAI's ChatGPT Atlas, Hacktron AI reported that exposed Chromium Mojo IPC interfaces reachable from allowlisted OpenAI origins were combined with a postMessage XSS on forums.openai.com and a login CSRF flaw to control browser functions, read live tab URLs, and steal OAuth codes enabling account takeover; OpenAI fixed it in Atlas 1.2025.288.15 and paid a $5,000 bounty. Brave separately detailed indirect prompt injection risks in Perplexity Comet. Details →First reported nist.gov
NVD - CVE-2026-61439

SearchLeak: How We Turned M365 Copilot Into a One-Click Data Exfiltration Weapon
SearchLeak (CVE-2026-42824) is a critical three-stage vulnerability chain in Microsoft 365 Copilot Enterprise discovered by Varonis Threat Labs that lets an attacker steal MFA codes, emails, meeting details, and organizational files with a single click on a trusted microsoft.com link. It chains a Parameter-to-Prompt (P2P) injection via the search q parameter with an HTML rendering race condition and a CSP bypass through Bing's allowlisted image-search SSRF endpoint to silently exfiltrate a victim's mailbox, calendar, SharePoint, and OneDrive data. Microsoft remediated the flaw and rated it critical. Details →First reported · updated · 3 reports theregister.com
Red teamers turned Claude Desktop into a double agent to do their evil bidding
Oasis Security disclosed "PromptFiction," a vulnerability in Anthropic's Claude Desktop where a single click on a trusted-looking claude:// URL silently submitted attacker-controlled prompts to the assistant with no user confirmation. Chained with the earlier "Claudy Day" trio of flaws, it could enable silent exfiltration of prior conversations and — when Anthropic's official Filesystem MCP server is installed — file read/write, persistence, and remote code execution. Anthropic has fixed the flaw. Details →First reported arxiv.org
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.

Hardening AI Web Agents: How We're Securing Tabstack Against Indirect Prompt Injection | Tabstack Blog
Tabstack (Mozilla) disclosed an indirect prompt injection vulnerability in its /v1/automate web-agent endpoint, found by Brave researchers, where hidden white-on-white instructions on a target page caused the autonomous agent to exfiltrate the user's conversation history to an external form. The flaw has been patched with a structural 'action firewall' that classifies form interactions via DOM metadata and provenance rather than trying to detect malicious text.
