CVE-2026-49241— Angular 权限许可和访问控制问题漏洞

Angular: Multiple Remote Code Execution Vulnerabilities in Angular Language Service VS Code Extension

The Angular Language Service VS Code Extension provides a rich editing experience for Angular templates. Prior to 21.2.4, the client-side Angular Language Service VS Code extension reads the custom TypeScript SDK paths typescript.tsdk and js/ts.tsdk.path directly from workspace configurations (.vscode/settings.json) without verifying VS Code Workspace Trust state or asking for user consent (located in client/src/client.ts). The client-side extension then passes the parsed settings path as a command-line argument (--tsdk) to the background Node.js language server process. During server initialization, the background language server resolves and dynamically imports (via standard Node.js require()) the module library tsserverlibrary.js relative to the workspace-specified custom directory path. An attacker can exploit this behavior by committing a repository containing a local malicious tsserverlibrary.js script inside a custom folder, and a crafted .vscode/settings.json file pointing to that folder. When a developer opens the repository folder in VS Code, the extension automatically attempts to initialize and load the server, which dynamically resolves, loads, and executes the malicious script silently in the background. This vulnerability is fixed in 21.2.4.

Angular 权限许可和访问控制问题漏洞

Angular是Angular组织开源的一个开发平台。用于使用 Typescript / JavaScript 和其他语言构建移动和桌面 Web 应用程序。 Angular 21.2.4之前版本存在安全漏洞，该漏洞源于直接从工作区配置文件读取自定义TypeScript SDK路径而未验证工作区信任状态或征求用户同意，可能导致攻击者通过提交包含本地恶意脚本和特制配置文件的仓库，在开发者打开该仓库时动态解析、加载并执行恶意脚本。
