The Rust Security Response WG announced CVE-2024-24576, which affects the Rust Standard Library on Windows.

TL;DR: Upgrade your Rust version to 1.77.2.

How Does it Affect Tauri as a Library?

Some Tauri organization repositories use batch files (cmd.exe under the hood) for developer environment tooling such as build scripts. No reviewed repositories use batch files for runtime code.

We don’t see additional risks for the Tauri project based on this CVE.

Nevertheless, we will update our CI systems to use the latest Rust version.

Is My Tauri App Affected?

In general you are possibly affected if you fulfil all of the below criteria:

You ship your app on Windows
Your project enables the Tauri v1 shell feature with "execute": true or the v2 shell-plugin with allow-execute permission
You allow arguments in the scope element of the shell feature
You pass untrusted input to cmd.exe or .bat/.cmd files and improperly validate the scope (🚩)

If any of these criteria are not fulfilled in your application you are likely NOT affected.

If you implement custom commands or logic written in your application that directly exposes the Rust Command with arguments provided at runtime, you may be affected. While not Tauri specific, this pattern could affect any Rust project.

Conclusion

Please upgrade your Rust version to 1.77.2 as soon as possible and distribute updates to your users.
