I posted a while back, tested the biggest open endpoints and they were properly secured, the issues just weren’t updated.
Note: Plex didn’t have SSL, and refused to implement it, until ~6 weeks after I created a POC token exploit. Here’s the GitHub repo I posted as a patch before they got their system in order: https://github.com/Fmstrat/plex-ssl. In other words, don’t give them too much credit.
Kavita. It started for comics and moved on to books. It supports OPDS, the standard by which readers like KOReader and Mihon connect to fetch books.
I have tried so many, Calibre (not good for graphic novels), Komga (very dated in comparison to Kavita), and more, but for both graphic novels and books, it won’t be beat.
@4dpancake92@lemmy.world if you like Komga, take a look at Kavita. I was happy with my switch.
