Impact
TurboWarp Desktop versions prior to version 1.8.0 allowed a malicious project or malicious custom extension (sandboxed or unsandboxed) to silently read arbitrary files from disk and upload them to a remote server due to the desktop app allowing unrestricted access to file:// and allowing unrestricted network access. The only required user interaction is opening the sb3 file or loading the extension. Pressing the green flag is not necessary.
The web version of TurboWarp is not affected.
Patches
The file:// access bug is resolved on TurboWarp Desktop 1.8.0 and later. Manually updating is likely to be required as many official distribution channels do not support automatic updates.
Additional mitigations are being developed for future versions.
Workarounds
Avoid opening sb3 files or loading custom extensions from untrusted sources such as those sent over chat messaging apps.
