CVE-2026-48122 Shopify CVE debrief

Who should care

Developers using the Ruby LSP VS Code extension, especially those working with Ruby projects, should be aware of this vulnerability and take steps to mitigate it. This includes verifying their extension version and being cautious with untrusted repositories. The vulnerability could lead to code execution with developer privileges if a malicious repository is opened and trusted.

Why it matters

The Ruby LSP VS Code extension vulnerability could lead to code execution with developer privileges if a malicious repository is opened and trusted. Developers should verify their extension version and be cautious with untrusted repositories.

• Code execution with developer privileges
• Potential for malicious code execution
• Need for version verification and updates
• Caution required when opening untrusted repositories

Technical summary

The Ruby LSP VS Code extension prior to version 0.10.4 has a security issue where several workspace-level settings could be overridden by a malicious repository. This could potentially lead to code execution with the developer's privileges. The issue is fixed in version 0.10.4 of the extension. The vulnerability arises from the extension's configurability, which can be exploited by a malicious repository to execute code with the developer's privileges. Developers using the Ruby LSP VS Code extension should verify their version and update to 0.10.4 or later.

Defensive priority

Developers using the Ruby LSP VS Code extension should verify their version and update to 0.10.4 or later. They should also be cautious when opening repositories from untrusted sources.

Recommended defensive actions

• Update the Ruby LSP VS Code extension to version 0.10.4 or later.
• Be cautious when opening repositories from untrusted sources.
• Verify the integrity of the Ruby executable, version manager executables, and Bundler `Gemfile` used at startup.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
