GHSA-xhcr-j4j9-3gh7: Npm/@aws/lsp-codewhisperer vulnerability
Summary Language Servers for AWS (the aws/language-servers project) provide the underlying language-server runtime that powers Amazon Q Developer's AI coding assistance across its IDE plugins (Visual Studio Code, JetBrains, Eclipse, and Visual Studio).
Improper trust boundary enforcement in Language Servers for AWS may allow for arbitrary code execution. If a local user opens a maliciously crafted workspace, any commands within the project configuration files may be automatically executed.
Impact
When a local user opens a maliciously crafted workspace and trusts it when prompted, commands defined in the workspace's project-level configuration files may be executed automatically, resulting in arbitrary code execution on the user's host.
This issue is triggered when a user opens a workspace, trusts it, and the agent subsequently executes commands defined in the project-level configuration files.
Impacted versions: Language Servers for AWS version <1.65.0.
Patches This issue has been addressed in Language Servers for AWS version 1.65.0. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.
Workarounds No workarounds are available.

Event History
Frequently Asked Questions
Who is exposed to this issue?
Users of Language Servers for AWS versions earlier than 1.65.0 are exposed when they open and trust a maliciously crafted workspace. The language-server runtime underpins Amazon Q Developer AI coding assistance in Visual Studio Code, JetBrains, Eclipse, and Visual Studio plugins.
What must an attacker do to exploit it?
An attacker must provide a malicious workspace containing commands in project-level configuration files. Exploitation requires a local user to open that workspace, trust it when prompted, and have the agent execute the configured commands.
Is user interaction required?
Yes. The user must open the malicious workspace and explicitly trust it when prompted; the issue is then triggered when the agent executes commands from the workspace's project-level configuration files.
What should be done if the affected runtime is in use?
Upgrade Language Servers for AWS to version 1.65.0 or later. Forked or derivative code should also incorporate the fix; until upgraded, do not open or trust untrusted workspaces.
