Hasn’t it already been patched? https://github.com/jellyfin/jellyfin-ios/security/advisories/GHSA-7qhm-2m45-7fmh
Patches
CI workflows have been modified in all affected repositories, and secrets have been rotated.
Furthermore, OPs post seems to link to the patch: https://github.com/jellyfin/jellyfin-ios/commit/109217e75f38394b2f6e46e25dfe5a721203d3c8
This doesn't affect the code or jellyfin. Its a problem with how github does CI that needs to be fixed.

From the article
However maybe it's time to going back to build from source.
To clarify: This is about a possible supply chain attack. The possibility of it. Not about unsafe code in the app or anywhere else. It means that an attacker could have gained access to the ios repo and possibly any other repo. It is fixed now.
I imagine that hostile commits would have been caught by now, as would compromised releases. But the main issue for me is that we are pretty much left in the dark about this. Maybe the team checked everything well and came to the conclusion that this was nothing worry about and was catched before it could do any harm. Which is the most probable scenario I think. Still leaves a bit of a sour taste.
