Tutanota (Tuta Mail) is an encrypted email provider. Tutanota allows users to open links in emails in external applications. Prior to version 3.118.12, it correctly blocks the `file:` URL scheme, which can be used by malicious actors to gain code execution on a victims computer, however fails to check other harmful schemes such as `ftp:`, `smb:`, etc. which can also be used. Successful exploitation of this vulnerability will enable an attacker to gain code execution on a victim's computer. Version 3.118.2 contains a patch for this issue.

NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
