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 Komga?

Komga is rewriting its web UI in the open, shipping the beta alongside the old one.

Komga's release cadence is dominated by NextUI, a ground-up rewrite of the web interface that landed in beta with 1.26.0 and is served next to the existing UI at /next rather than replacing it. The three patch releases that followed within 48 hours were almost entirely NextUI shakedown work — scroll restoration, selection behavior, stylesheets failing to load under Tomcat. Underneath the interface work the server keeps widening format support, with rar5 handling in plain Java and solid rar4 archives earlier in the summer.

◆ 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.

6.3

Komga is rewriting its web UI in the open, shipping the beta alongside the old one.

◆ Current state

Komga's release cadence is dominated by NextUI, a ground-up rewrite of the web interface that landed in beta with 1.26.0 and is served next to the existing UI at /next rather than replacing it. The three patch releases that followed within 48 hours were almost entirely NextUI shakedown work — scroll restoration, selection behavior, stylesheets failing to load under Tomcat. Underneath the interface work the server keeps widening format support, with rar5 handling in plain Java and solid rar4 archives earlier in the summer.

◆ Where it's heading

The project is running a long, deliberately cautious frontend migration: both UIs ship in the same binary, the feature gap is tracked publicly in an issue, and users opt in by URL. That arrangement should persist across several minor versions before the old WebUI is retired. The parallel v2 referential API suggests the rewrite is also being used to revise the server contract rather than only restyle the client.

◆ Prediction

Near-term releases should keep closing the NextUI feature gap issue by issue, with patch releases landing within days of each other. The old WebUI is unlikely to be removed before NextUI reaches parity and browser refresh stops falling back to it.
