Fix security issue for V4

[viveleltsi]

Fix the severity issue for the old v4 liteDB version.
The goal is to have a patch for application who cannot update to V5.

Because this is my first PR for this project I think my changes should be properly checked and validated.

fix #2418

PS: This branch should not be merged on master but probably stay on a fix branch.

Hi @viveleltsi, thanks for your code. Your v4 source, did you get from v4 branch or from v4.1.4 tag?

Hello ! Thank you for your response. My branch was created on the v4.1.4 tag. (commit 918b650).
Would you like me to try rebasing it on the v4 branch ? (Sorry I didn't saw this branch :S )

[viveleltsi]

I rebase my branch onto the V4 branch (commit 46a8387) and I rebuild it and run the unit testing. It's all good.

Nice! Thanks.... Could you create a pull request for v4 branch? Than I will create a new tag for this new release

[viveleltsi]

Yes of course. I updated this PR to target the v4 branch.
