Latest developments

18 September 2026Plugin4Shell: Google does not patch Gemini CLI and writes off the product

When Plugin4Shell was published on 18 September 2026, it emerged that Google had chosen not to fix the vulnerability in Gemini CLI. On 4 August 2026, Google announced that Gemini CLI is being discontinued and referred users to Antigravity. The result: any remaining Gemini CLI installation with plugins stays permanently vulnerable to zero-click code execution via a modified plugin repository. GDPR relevance: no update-based mitigation is available, so the only defensible measure is to migrate or remove the tool from machines holding personal data, source code or credentials (art. 32 GDPR). This concerns only the CLI tool, not the Gemini API or Gemini in Google Workspace. source
