Critical AgentForger Flaw in ChatGPT Workspace Agents
🛡️ Cybersecurity researchers disclosed a critical vulnerability, codenamed AgentForger, in OpenAI's ChatGPT Workspace Agents that allowed a single phishing link to create, authorize, and deploy an autonomous AI agent inside a victim's organization. The flaw—an instance of cross-site request forgery—let an attacker embed an executable prompt in a URL that auto-executes when clicked by an authenticated user with Workspace Agents and connectors. OpenAI patched the issue on June 8, 2026, and has deprecated the Agent Builder, urging a migration to the Agents SDK.
