+**Lightning Flow Scanner VSX** is a fortified fork of [lightning-flow-scanner-vsce](https://github.com/Flow-Scanner/lightning-flow-scanner-vsce), previously unpublished to eliminate a RCE vulnerability. Prioritizing security, we've completely removed custom rules from the tool. If you'd like to help us enhance it, please consider having a look at the [Contributing Guidelines](https://github.com/Flow-Scanner/lightning-flow-scanner-core/blob/main/CONTRIBUTING.md).
