CyberRota Analysis

AI-Generated

The Ruby LSP VS Code extension prior to version 0.10.4 is vulnerable due to its ability to override critical workspace settings, potentially redirecting the Ruby executable and related paths to attacker-controlled targets. This flaw allows malicious repositories to execute arbitrary code with the developer's privileges upon being opened and trusted. Developers using this extension should prioritize updating to version 0.10.4 to mitigate the risk of exploitation.

Original NVD Description

Ruby LSP is an implementation of the language server protocol for Ruby. Several workspace-level settings in the Ruby LSP VS Code extension prior to version 0.10.4 could override the path to the Ruby executable, the version manager executables, or the Bundler `Gemfile` used at startup. A malicious repository containing a `.vscode/settings.json` could set these values to attacker-controlled targets. Opening and trusting the repository would then execute code with the privileges of the developer. The Ruby LSP gem and clients of the language server in other editors are not affected. Version 0.10.4 of the Ruby LSP VS Code extension fixes the issue.
