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 pagedown?

pagedown is down to one small fix a year, mostly absorbing changes from elsewhere.

The last six releases contain no new capability. 0.24 fixes missing horizontal rules under unnumbered h1 headers in the poster_jacobs format; 0.23 stops non-ASCII header text erroring during TOC processing; 0.22 drops a call to `xfun::attr()` before it disappears upstream; 0.21 sets an `is.paged.js` knit option so knitr knows paged.js loads its own JS and CSS; 0.20 raises the R floor; 0.19 patches a browser rendering regression with `overflow-x: clip`.

CommaFeed is patching its way through the attack surface a self-hosted reader inherits

◆ 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.

0.0

pagedown is down to one small fix a year, mostly absorbing changes from elsewhere.

◆ Current state

The last six releases contain no new capability. 0.24 fixes missing horizontal rules under unnumbered h1 headers in the poster_jacobs format; 0.23 stops non-ASCII header text erroring during TOC processing; 0.22 drops a call to `xfun::attr()` before it disappears upstream; 0.21 sets an `is.paged.js` knit option so knitr knows paged.js loads its own JS and CSS; 0.20 raises the R floor; 0.19 patches a browser rendering regression with `overflow-x: clip`.

◆ Where it's heading

pagedown sits between three things it does not control — paged.js, headless Chrome, and Pandoc — and its release history is a record of each of them moving. The one release in the window with anything resembling design intent is 0.21, which lets other packages detect a paged.js context rather than guess it. Cadence has thinned to roughly one release a year, and the last genuinely new features (long-table headers, Sass support, streamed PDF transfer) are outside this window.

◆ Prediction

Expect another single-fix release triggered by a paged.js, Chrome or Pandoc change. Nothing here suggests new output formats are coming.
