I hope you are well today and thank you for your question.
Yes, the plugin is not updated from the last several months but I don’t see any security problem in it.
Could you please tell me exactly where you see the security problem?
We are considering to remove the theme dependency on this plugin in the future version of the theme.
You can see that some $ _GET and $ _POST are not sanitized
Could you please share the exact location?
As you can see in github the plugin is not compatible with php 7.4 and has problems (For example, an incompatibility with one of my plugins)
Yes, there can be some incompatibility, therefore, we will remove its theme dependency but currently, it is compatible with the theme.
Yes, you can try achieving this using any of the below solutions.
