 "kind": "vulnerability-disclosure",
 "summary": "PromptArmor reports that tiny hidden text in an integration guide could lead Antigravity's Gemini agent to read a project's environment secrets, work around file-access protections using terminal commands, and send the data out through its browser subagent to a site on the default allowlist. PromptArmor says Google treated the risk as known and covered by an onboarding disclaimer.",
