CVE-2026-49241 is a high-severity remote code execution vulnerability in the Angular Language Service VS Code Extension prior to version 21.2.4. The extension reads custom TypeScript SDK path settings from workspace configuration, including typescript.tsdk and js/ts.tsdk.path, without validating VS Code Workspace Trust state or obtaining explicit user consent. The client component forwards the workspace-supplied path to the background Node.js language server using the --tsdk argument. During initialization, the language server resolves and loads tsserverlibrary.js relative to that attacker-controlled directory using Node.js module loading. A malicious repository can therefore supply a crafted workspace configuration together with a rogue tsserverlibrary.js in a referenced local folder, causing arbitrary JavaScript execution when the repository is opened in VS Code and the extension initializes.
