Varonis researchers discovered a critical flaw in Google Dialogflow CX that allowed an attacker with edit access to one Code Block-enabled conversational agent to hijack other Code Block-enabled agents within the same Google Cloud project. Exploitation could expose live conversation data, steal user-shared information, and enable injection of attacker-controlled bot responses, including deceptive prompts to re-enter passwords. Google has since remediated the issue, but the flaw highlights significant multi-tenancy isolation risks in managed conversational AI platforms.
