Tuta 从外部资源加载图片。
漏洞描述信息
Tuta是一种加密电子邮件服务。在版本119.10之前的版本中，攻击者可以在HTML邮件中附加一个从外部资源加载的图像，即使默认情况下应该禁止加载外部资源。当显示包含外部内容的电子邮件时，它们应该由用户确认后才能被加载。然而，某些嵌入图像（参考PoC）尽管“自动重新加载图像”功能默认情况下已经禁用，仍然会被加载。这种行为对于用户来说是意外的，因为用户假定外部内容只有在用户手动确认后才会被加载。电子邮件中包含外部内容会带来一个风险，因为这使得发送者意识到电子邮件地址正在被使用，电子邮件已经被读取，使用了哪种设备和暴露了用户的IP地址。版本119.10包含一个修复此问题的补丁。

Tuta loads images from external resources
漏洞描述信息
Tuta is an encrypted email service. In versions prior to 119.10, an attacker can attach an image in a html mail which is loaded from external resource in the default setting, which should prevent loading of external resources. When displaying emails containing external content, they should be loaded by default only after confirmation by the user. However, it could be recognized that certain embedded images (see PoC) are loaded, even though the "Automatic Reloading of Images" function is disabled by default. The reloading is also done unencrypted via HTTP and redirections are followed. This behavior is unexpected for the user, since the user assumes that external content will only be loaded after explicit manual confirmation. The loading of external content in e-mails represents a risk, because this makes the sender aware that the e-mail address is used, when the e-mail was read, which device is used and expose the user's IP address. Version 119.10 contains a patch for this issue.
