漏洞描述信息
MIT 长期 kindergarten Scratch Scratch-vm 在 0.2.0-prerelease.20200714185213 之前加载了某些 _ 字符的不信任项目.json 文件，导致远程代码执行，因为 URL 的内容被处理为脚本，并作为 workers 执行。负责代码是serialization/sb3.js 中的 getExtensionIdForOpcode。使用 _ 与较早版本的保护机制不兼容，在较早的版本中，URL 被拆分，从而防止了 deserialization 攻击。注意：由于缺少 worker 脚本，Scratch.mit.edu 托管服务未受影响。

漏洞描述信息
MIT Lifelong Kindergarten Scratch scratch-vm before 0.2.0-prerelease.20200714185213 loads extension URLs from untrusted project.json files with certain _ characters, resulting in remote code execution because the URL's content is treated as a script and is executed as a worker. The responsible code is getExtensionIdForOpcode in serialization/sb3.js. The use of _ is incompatible with a protection mechanism in older versions, in which URLs were split and consequently deserialization attacks were prevented. NOTE: the scratch.mit.edu hosted service is not affected because of the lack of worker scripts.
