Description
Twine 2 desktop through 2.12.0 contains a cross-site scripting vulnerability in importStories() that executes markup from imported story files in the editor window. Attackers can craft a story file whose script calls the twineElectron openWithScratchFile IPC bridge to write and open a .bat file, executing code as the user.
