Technical details

A 'Zip Slip' (path traversal) vulnerability exists in Streambert's subtitle extraction logic within `src/ipc/subtitles.js`. The application fails to sanitize archive entry filenames when processing ZIP files downloaded via the `get-subtitle-url` IPC channel. By concatenating raw entry names directly to the temporary directory path, the application allows specially crafted ZIP files containing `../` sequences to escape the intended directory. An attacker can exploit this to write arbitrary files to the host filesystem with the permissions of the application. The vulnerability has been addressed in version 2.5.0 by implementing `path.basename()` sanitization on extracted filenames.
