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.
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。
