Description
A mutation cross-site scripting (XSS) issue in Typora through 0.9.9.31.2 on macOS and through 0.9.81 on Linux leads to Remote Code Execution through Mermaid code blocks.

Given that the application is based on the Electron framework, the XSS leads to remote code execution in an unsandboxed environment.
