CommaFeed vs Jellyfin: at a glance
What is CommaFeed?
CommaFeed is patching its way through the attack surface a self-hosted reader inherits
CommaFeed's 7.x line has become a sustained security pass. The newest patch closes Host header injection on the password recovery endpoint and adds a commafeed.password-recovery-public-base-url setting so the email base URL is configured rather than taken from the request. Behind it: local address blocking made secure by default alongside Google Reader API support in 7.3.0, javascript: URLs filtered at parse time in 7.2.1, and SSRF limits on the image proxy in 7.2.0.
What is Jellyfin?
Jellyfin renumbers to 12.0 and spends the whole cycle paying down its backend rewrite.
Jellyfin is deep in a 12.0 release-candidate train — five RCs since late June — that exists almost entirely to stabilize the backend rewrite shipped in 10.11.0. The project also renumbered along the way: 10.11.x becomes 12.x, dropping a leading "10." that had made every release read as minor. The outgoing 10.11.x stable line is still getting fixes, but 10.11.11 is down to a single locking change.

◆ Current state
CommaFeed's 7.x line has become a sustained security pass. The newest patch closes Host header injection on the password recovery endpoint and adds a commafeed.password-recovery-public-base-url setting so the email base URL is configured rather than taken from the request. Behind it: local address blocking made secure by default alongside Google Reader API support in 7.3.0, javascript: URLs filtered at parse time in 7.2.1, and SSRF limits on the image proxy in 7.2.0.
◆ Where it's heading
Every release in this stretch closes a path where content or a request from outside the instance was trusted too far - feed URLs reaching internal addresses, proxied images, javascript: links, and now a header shaping an outbound email. That is the checklist of a project being run as a multi-user hosted service rather than a single-user tool, and it follows directly from the 7.0.0 decision to sandbox filter expressions. Feature work continues in parallel but is clearly the smaller half.
◆ Prediction
The remaining untrusted-input surfaces - OPML import and the feed fetcher's redirect handling - are the likely next targets. The pattern of shipping each fix as its own patch release should continue rather than batching them.
Jellyfin
5.0COLLAB
Jellyfin renumbers to 12.0 and spends the whole cycle paying down its backend rewrite.
◆ Current state
Jellyfin is deep in a 12.0 release-candidate train — five RCs since late June — that exists almost entirely to stabilize the backend rewrite shipped in 10.11.0. The project also renumbered along the way: 10.11.x becomes 12.x, dropping a leading "10." that had made every release read as minor. The outgoing 10.11.x stable line is still getting fixes, but 10.11.11 is down to a single locking change.
◆ Where it's heading
The RC rounds are getting narrower as the train converges. RC1 was a cumulative dump covering the move to .NET 10, removal of legacy API route middleware and deprecated API members, and an HLS transcode seeking refactor; RC5 is batched database lookups and a fix for image endpoints upscaling past the source resolution. The 10.11.x branch is now being maintained mainly as an upgrade floor — 12.0 refuses to install on anything older than 10.10.7 and runs a multi-minute migration on first boot.
◆ Prediction
With RC5 down to query batching and individual endpoint fixes, a 12.0 final looks near — likely one or two more RCs at most. The plugin story is the loose end: the RCs still tell testers to disable external plugins and reinstall from the unstable repository, and that has to resolve before a general release.
