TCC bypass via enabled Electron Node fuses
Published Jan 8, 2025 · Updated Jan 8, 2025
Code injection in Eugeny Tabby before 1.0.217 allows local users to bypass macOS TCC and access protected resources. The packaged Electron binary leaves RunAsNode, EnableNodeOptionsEnvironmentVariable, and EnableNodeCliInspectArguments enabled, so attacker-controlled environment variables or inspector flags execute Node.js code in Tabby's signed context. Local code execution is required; injected child processes inherit previously granted access to personal folders, the camera, and the microphone without further prompts.
