Received security vulnerability alert

Hello, I have received a security alert about this plugin, that it contains a security vulnerability. I see that the plugin is also no longer available for download here. The last update was from 7 years ago, is this still being worked on or has the plugin been abandoned? I have been using the plugin for years without any problems, and I would like to continue using it. I’d love to hear if anyone is still working on it and if the security issue can be resolved.
