Unverified Flatpak found with major security vulnerability

I noticed that a package I was looking for, Synology Drive has not been updated for 7 months as has a major security vulnerability. I reported it on the Git, but no response or acknowledgment. Is there no way to report it on FH itself?

Install Synology Drive client from the Synology Support Download Center I have it on my system and currently at version 3.5.1-16102

The maintainer seems inactive, I went ahead and merged a pending update which updates it to 3.5.1-16101
