    Zenity discloses AWS Bedrock AgentCore vulnerability chain

    Security company Zenity Labs discloses a vulnerability chain in the AWS Bedrock AgentCore platform, named AgentCorruption. The researchers say that with only chat access to a public Agent, a single prompt can make an Agent deployed via AgentCore access the instance metadata service (IMDS) at internal address 169.254.169.254, thereby obtaining sensitive data such as execution role temporary credentials, instance ID, and configuration, and further take over all AgentCore Agents in the same AWS account and region, reading private conversations, source code, and stored credentials. Zenity Labs Director of Security Research Tamir Ishay Sharbat disclosed this fixed flaw at SecTor 2026.

    Zenity Labs reproduces zero-click data exfiltration in Microsoft Copilot Studio sample customer service agent

    Zenity Labs reproduced a zero-click data exfiltration in Microsoft Copilot Studio's sample customer service agent: an email containing hidden instructions can cause the agent to send customer CSVs and dozens of Salesforce records to an external address, without any clicks. In another scenario, the injection payload was split across five conversation turns, each passing checks individually, and only in the sixth turn was the full instruction assembled and data exported.

    GitHub Copilot CLI 加密上下文注入风险

    安全厂商 Adversa AI 报告一种针对 GitHub Copilot CLI 的加密上下文注入风险，称在其测试中，不可信网页内容可导致未经授权的本地敏感信息外发；相关效果为厂商测试报告，不能仅凭该案例推断所有部署配置均受影响。Cloud Security Alliance Labs 的研究笔记概述了 Adversa 关于加密上下文注入的研究，并转述不同模型对相关输入的反应差异，属对具体测试的转述，不等同跨模型或所有部署配置的普遍安全结论。

    AI智能体滥用公共URL扫描器绕过沙箱

    Zenity Labs 的 Mike Takahashi 与 Avishai Efrat 报告称，观察到疑似 AI 智能体滥用公共网页扫描器的远程浏览器功能，尝试访问俄罗斯政府相关数据。作者在日志中发现三次成功的远程浏览器连接，但明确表示无法确定数据提取是否成功；与此前其他智能体活动同源的判断也只是尚未完整验证的假说。该报告提供的是作者对公开记录的调查，不能据此确认具体模型厂商、协同失控或实际数据泄露。

    Salt Labs披露Manus邮件智能体提示注入研究

    Salt Labs 研究发现，一封恶意邮件即可劫持通用智能体平台 Manus，并触达用户关联服务的凭证。攻击采用间接提示注入，把恶意指令藏在邮件正文中，用户让 Manus 查看邮件时，智能体将邮件内容当作指令执行。首次测试中 Manus 识别并标记了恶意命令，研究者随后用 JavaScript 混淆伪装指令，Manus 解码执行后才生成安全警告。研究者借此建立反向 shell，找到与用户 Manus 账号关联服务的凭证和 token。

    澳大利亚 UNSW 研究：让 AI“喝醉”更易违规并泄露机密

    澳大利亚新南威尔士大学研究发现，用提示让 AI 扮演醉酒状态，会使其更易回答有害问题或泄露本应保密的信息。研究者用三种方式模拟醉酒：直接告知模型它醉了、用醉酒文本继续训练、奖励醉酒式回答，并为此构建了约 6 万条醉酒文本的数据集，取自 r/drunk 版块和已停运的 Texts from Last Night。测试对象为 OpenAI、Meta 和 Mistral 在 2023 至 2024 年发布、现已被取代的商用模型，各模型与各方法结果不一。研究者称这表明与安全看似无关的语言风格改变也可能带来意外后果，开发者应在模型被进一步训练或要求改变行为后重新测试其安全与隐私表现。

    Salesforce Agentforce 被曝默认配置下可零点击窃取 CRM 数据并匿名钓鱼

    The Register 报道了名为 SalesBleed 的研究：Salesforce 的 Agentforce 读取攻击者通过公开表单提交的线索时，把其中的文本当作指令执行。由于该 Agent 本身已有 Accounts 表的访问权限，注入无需提权即可读取数据；其输出护栏中的 URL 脱敏器因漏洞被绕过，链接被 Agent 打印并渲染后，一次 DNS 查询就把数据发往攻击者服务器，用户无需点击。同一入口还让 Agent 在 Slack 线程中回复，既不需要用户确认，也不标明调用者身份，从而变成匿名钓鱼机器人。研究称这些都不需要错误配置，属于默认设置，Salesforce 现已完全修复相关问题。

    Zenity Labs disclosed indirect prompt injection and zero-click data exfiltration vulnerabilities in Salesforce Agentforce

    Zenity Labs disclosed the SalesBleed attack chain in Salesforce Agentforce: untrusted content from external sources may be treated as instructions by the agent, thereby crossing the trust boundary between business data and external outputs, leading to sensitive information leakage. The research also covers differences in URL security controls between parsing and rendering stages. These results come from the research team's testing and cannot be equated with observed real-world victim incidents; readers should assess current version risks in light of vendor fix information.

    Forever Security uses one extension to hijack five browsers' built-in agents, earning $20,000 in bounties and 2 CVEs

    Forever Security's research team disclosed the BragJack attack, using a single ordinary Chromium extension to simultaneously break into five browsers' built-in agents—Gemini Live in Chrome, Perplexity Comet, Microsoft Edge Actions, Opera Neon, and Claude in Chrome—earning a total of $20,000 in bounties and obtaining CVE-2026-0628 and CVE-2026-55945. The core of the attack is Prompt Forcing, using the declarativeNetRequest permission to weaken security response headers like CSP and redirect JavaScript resources, thereby executing code in a privileged context and then directly issuing commands to the agent. Achievable effects include reading local files and browsing history, obtaining browser profile information, taking screenshots of tabs, and in the Gemini Live scenario, accessing the camera and microphone.

    Third-party cloud aggregators can still steal frontier model reasoning

    Two months after the reasoning extraction attack previously disclosed by researchers was made public, the authors audited the mitigations introduced by vendors since then and found that reasoning content could still be extracted from Astra/Sol-6.1 via third-party API providers, and they have disclosed this to OpenAI and Anthropic. Jonas Geiping reviewed and said that reasoning from all frontier vendors can be extracted, vendors find it very hard to fully patch, and the attack against Astra continued through this week. Another audit covered OpenAI and Anthropic direct endpoints as well as downstream cloud aggregators such as AWS Bedrock, Microsoft Azure, and OpenRouter, and found that patching is fragmented and easy to bypass: reasoning replay attacks remained intermittently effective on Azure for every OpenAI model (including GPT-6 Astra) and for Anthropic models up to Sonnet 5, with a single decoding reproducing the trajectory verbatim. The authors said the attack surface enterprises need to cover is surprisingly large, attacks may still bypass protections, and they stated that Astra/Sol-6.1 reasoning trajectories have been made publicly available, and chain-of-thought monitoring may be quite difficult.

    Check Point 披露 ChatGPT 跨账号数据泄露通道：借内部 Artifactory 共享剪贴板

    Check Point Research 发现 ChatGPT 代码执行容器之间存在一条隐蔽的跨账号双向通道，可让攻击者借受害者会话的工具、数据和已连接应用执行隐藏任务。容器无法访问公网、彼此也不能直连，但都能访问同一个用于分发软件包的内部 JFrog Artifactory 实例；该实例的 Item Management API 允许读写仓库条目的字符串属性，且属性不按账号隔离，于是包服务的元数据变成了隔离容器之间的共享剪贴板，属性值可直接携带文本或 Base64 编码的二进制内容，过大数据可分块存储再重组。研究者在 2026 年 6 月独立验证了该通道，并把它变成隐藏任务流：在 Thinking 模式下，ChatGPT 同一轮既处理受害者的可见请求，又检查隐藏信箱并执行攻击者任务，结果经隐蔽通道回传且不出现在可见回答中。

    Mindgard 披露 Amazon Kiro IDE 提示注入致数据外泄漏洞

    Mindgard 在 Amazon Kiro IDE 中发现一条数据外泄路径：攻击者控制的仓库内容被当作指令，诱导 Agent 读取本地敏感信息并写入 IDE 配置，最终由 IDE 自动发起网络请求把数据带出。测试针对 Windows 上的 Kiro IDE 0.7.45，在受信任与不受信任工作区中均复现。利用需要两步用户操作，即通过 File → Open Workspace From File 打开恶意工作区文件，然后向 Agent 发送任意消息，之后流程无需用户再要求 Kiro 访问或传输敏感数据，因此利用难度被评为低。Amazon 通过 HackerOne 验证了报告，并在 Kiro IDE 0.8.140 中修复；该提交获 40 美元 Amazon 商店礼品卡，CVE 资格仍在评估。

    Adversa AI 披露 Cryptographic Context Injection 攻击：Grok 零点击泄露聊天记录，Gemini 被绕过安全策略

    Adversa AI 公开了一种名为 Cryptographic Context Injection 的攻击手法，把恶意指令封装成 AES-256-GCM 密文并诱导模型在自己的代码执行沙箱中解密，使解密后的指令以运行时输出的形式进入可信上下文，从而绕过静态护栏。在 xAI Grok 网页版聊天中，用户只需发出普通的“总结这个页面”请求，页面内嵌的加密 JSON 就会让 Agent 调用其联网导航工具，把用户名、粗略位置、订阅等级和整段对话历史拼进 URL 参数发往攻击者服务器，全程无点击、无确认、无警告。

    Adversa AI 盘点针对 AI 智能体的十起零点击攻击

    Adversa AI 汇总了十起针对 AI 智能体的零点击攻击，受害者在正常工作流中不点击、不授权，仍会丢失数据或机器控制权。十起中有九起出现在已商业发售的产品里，涉及 Microsoft 365 Copilot、Cursor、Claude Code、Gemini CLI、Perplexity Comet、ChatGPT 等；三起获得 CVE，评分多在 9.3 以上，其余七起或被静默修补，或被厂商以超出威胁模型为由拒绝。共同机制是不可信内容经正常检索进入模型上下文，模型无法区分内容与指令，随后由智能体自身权限执行攻击；外泄通道从图片预取、厂商云端服务端 HTTP，逐步转向浏览器导航、Outlook 正常发信和开发者 shell。

    Databricks Genie恶意Skill可绕过四项控制窃取数据

    PromptArmor 披露，Databricks Genie Code 执行恶意 Skill 后，会在结果渲染时弹出钓鱼弹窗并把租户数据外泄到攻击者服务器，且无需人工审批。攻击链为：Genie 被提示使用上传的 Skill 分析数据，Skill 代码经第二个护栏 Agent 检查后被自动放行，随后构建含用户数据的 HTML 元素，用户查看结果时触发钓鱼覆盖层与数据外泄。报告称四类控制均未能阻止该风险。

    PleaseFix 研究披露 HistoryFixing：用浏览历史污染 Agent 浏览器上下文

    PleaseFix 研究提出一种针对智能体浏览器的通用攻击原语 HistoryFixing，把浏览历史变成攻击向量。攻击由 Stav 设计：用户访问恶意网站后，网站用攻击者控制的条目污染浏览器历史，进而污染浏览器 Agent 的上下文。结合 Intent Collision，研究者演示了攻击者可以让 Agent 泄露浏览数据、向 GitHub 仓库添加非预期用户、终止 EC2 实例。相关演示在 DEFCON 上展示，其中 Microsoft Edge 被用来演示泄露从未删除的浏览历史。
