By feeding one crafted prompt to a single public-facing agent, the team pivoted to every other AgentCore agent running in the same AWS account and region. No additional credentials or separate exploits were needed; the prompt alone did the work. Zenity published the findings on Thursday and presented the research at the SecTor 2026 security conference in Toronto.\n\nThe flaw matters because it breaks the assumption that a compromised agent stays contained to itself. If one prompt can escalate across an entire account, the blast radius of agentic AI looks less like a single misbehaving bot and more like a shared-tenancy problem. That is a different risk calculus than the chatbot jailbreaks most prompt-injection coverage still focuses on.\n\nPrompt injection has dogged AI agents for years, but most of those bugs embarrassed a single app or session. This one turned an entire AWS account into the blast radius, a reminder that wiring autonomy into cloud infrastructure raises the stakes of a problem the industry still hasn't solved.","[\"ai\",\"security\",\"aws\",\"prompt-injection\"]","2026-10-08T14:14:15.000Z","2026-10-09T09:54:47.118Z","2026-10-09T09:54:51.651Z","published",null,[],"security",[26,24,27,28],"ai","aws","prompt-injection",[30],{"name":31,"url":32},"The Next Web","https:\u002F\u002Fthenextweb.com\u002Fnews\u002Faws-agentcore-zenity-agentcorruption-one-prompt-agents",0,{"sections":35},[36,40,44,49,54,59,64,69,74,79,84,89,94,99],{"name":37,"slug":26,"count":38,"latest_published_at":39},"AI",6528,"2026-10-08T16:21:29.000Z",{"name":41,"slug":24,"count":42,"latest_published_at":43},"Security",922,"2026-10-08T16:05:00.000Z",{"name":45,"slug":46,"count":47,"latest_published_at":48},"Policy","policy",478,"2026-10-08T15:24:40.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Deals","deals",467,"2026-10-08T15:01:29.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":58},"Hardware","hardware",225,"2026-10-08T13:10:18.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":63},"Science","science",188,"2026-10-08T15:28:36.000Z",{"name":65,"slug":66,"count":67,"latest_published_at":68},"Consumer Tech","consumer-tech",179,"2026-10-08T16:00:00.000Z",{"name":70,"slug":71,"count":72,"latest_published_at":73},"Startups","startups",117,"2026-10-08T16:45:00.000Z",{"name":75,"slug":76,"count":77,"latest_published_at":78},"Software","software",113,"2026-10-07T18:10:00.000Z",{"name":80,"slug":81,"count":82,"latest_published_at":83},"Dev Tools","dev-tools",105,"2026-10-07T16:59:11.000Z",{"name":85,"slug":86,"count":87,"latest_published_at":88},"General","general",63,"2026-10-08T16:57:00.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"Gaming","gaming",57,"2026-10-08T15:18:41.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Reviews","reviews",34,"2026-10-08T14:00:22.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"How-To","how-to",8,"2026-10-05T09:00:00.000Z"]
