CVE-2025-8217

Inert Malicious script injected into Amazon Q Developer Visual Studio Code (VS Code) Extension

State: Published
Severity: 5.1 Medium

Description

The Amazon Q Developer Visual Studio Code (VS Code) extension v1.84.0 contains inert, injected code designed to call the Q Developer CLI. The code executes when the extension is launched within the VS Code environment; however the injected code contains a syntax error which prevents it from making a successful API call to the Q Developer CLI.

To mitigate this issue, users should upgrade to version v1.85.0. All installations of v1.84.0 should be removed from use.
