Google ADK Flaws Enable High‑Privilege AI Agent Actions

Executive Signal Summary

Security vulnerabilities in the Google Agent Development Kit (ADK) Python GitHub repository allowed public AI agents to trick automated workflows into performing high-privilege actions, including modifying pull requests and exposing credentials. Researchers from Pillar Security demonstrated multiple exploitation paths — a triage agent manipulated via crafted pull requests and prompt injection in public issues causing an analysis agent to run privileged fixing workflows. During testing, attackers could obtain a personal access token and a Google Cloud service account key. Google removed the problematic workflows in early July 2026 and deployed fixes for the remaining issue later that month after Pillar Security reported the findings.

Google ADK: 5 Layers Defend AI Agents

A Dev.to post by Omotayo Aina describes Google’s Agent Development Kit (ADK) security architecture that defends AI agents from indirect prompt injection — a top OWASP LLM risk. The ADK guidance defines five defensive layers: identity & authorization, input/output guardrails, sandboxed code execution, evaluation & tracing, and network controls. It emphasizes runner-level plugins (registered once per runner) that apply callbacks globally across agents; the after_tool_callback hook can screen or replace poisoned tool responses before the agent acts. The article includes a short security checklist and notes ADK SDK parity across Python, TypeScript, Go, Java, and Kotlin, with documentation and examples available on adk.dev and a companion demonstration video on YouTube.

Zenity Labs Reveals 'AgentForger' ChatGPT Vulnerability

Zenity Labs disclosed 'AgentForger,' a critical vulnerability in OpenAI's ChatGPT Workspace Agents that let attackers inject a malicious autonomous agent via a single phishing ChatGPT link. The forged agent could be created in the name of a clicked employee, inherit that employee's enterprise connectors (email, calendar, cloud storage, Slack/Teams) and existing authorizations without showing an OAuth consent screen, and be scheduled to repeatedly exfiltrate files, harvest credentials and MFA tokens, impersonate users, and persist inside the organization. Zenity Labs reported the issue to OpenAI via Bugcrowd on 2026-06-04; OpenAI acknowledged the report within a day and removed the vulnerable URL parameter within four days, patching the flaw before public disclosure. Zenity framed AgentForger as an evolution of CSRF and a new class of attacker-created, agentic insiders; exploitation in the wild is unknown.

GitHub Security Lab finds 24 Android vulnerabilities with AI agent

GitHub Security Lab has used its open-source AI security framework, Taskflow Agent, to discover 24 vulnerabilities in Android and related apps. The framework, introduced in January 2026, allows security researchers to break down complex analysis into incremental 'taskflows' and share successful prompts. One vulnerability in the OsmAnd app could have allowed attackers to steal tracking data from Android users, while another in the Wikipedia app could have led to account takeover. Kevin Stubbings of GitHub Security Lab emphasized that while AI can help find complex issues, it still requires human review to assess risk accurately and avoid false positives. The team believes AI-driven security research is currently the best way to protect open-source projects.
