Vertex AI SDK Bucket Squatting Flaw Enables Model Hijack

Vertex AI SDK Bucket Squatting Flaw Enables Model Hijack

ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 8.5 The Hacker News

A vulnerability in the Google Cloud Vertex AI Python SDK allowed unauthenticated attackers to intercept model uploads by pre-registering predictable staging bucket names — a technique Unit 42 calls 'Pickle in the Middle'. Once a malicious model replaced the legitimate upload, arbitrary code executed inside Google's serving infrastructure via pickle deserialization. Google patched the flaw in v1.148.0 after disclosure in March 2026, but the incident highlights systemic risks in ML pipeline supply chains.

CVE-2026: Anthropic MCP SDK Remote Code Execution

ATLAS OWASP CRITICAL Active exploitation · Immediate action required ▲ 9.4 The Hacker News

A systemic 'by design' vulnerability in Anthropic's Model Context Protocol (MCP) SDK enables arbitrary remote code execution across all supported language implementations via unsafe STDIO transport defaults, affecting over 7,000 publicly accessible servers and 150 million downloads. The flaw has been independently confirmed across 10+ popular AI frameworks including LiteLLM, LangChain, and Flowise, with Anthropic declining to modify the protocol's architecture. This represents a significant AI supply chain risk with cascading exposure to sensitive data, API keys, and internal systems.
