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 rmarkdown?

rmarkdown's job now is absorbing Pandoc's deprecations before users see them.

rmarkdown is at 2.31. Its releases read as a compatibility layer: switching to --syntax-highlighting for Pandoc 3.8 because --highlight-style is deprecated, dropping a syntax-highlighting workaround made unnecessary by Pandoc 2.18 three years ago, restoring table row classes that a Pandoc change removed, and falling back to html_document when a YAML output format is unrecognised.

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.

rmarkdown's job now is absorbing Pandoc's deprecations before users see them.

◆ Current state

rmarkdown is at 2.31. Its releases read as a compatibility layer: switching to --syntax-highlighting for Pandoc 3.8 because --highlight-style is deprecated, dropping a syntax-highlighting workaround made unnecessary by Pandoc 2.18 three years ago, restoring table row classes that a Pandoc change removed, and falling back to html_document when a YAML output format is unrecognised.

◆ Where it's heading

The package is stable and mostly defensive. Each release absorbs a change in Pandoc or knitr so documents keep rendering, with the occasional user-facing escape hatch — the rmarkdown.files.suffix option exists because the default _files directory made cloud sync tools delete HTML output. Little here extends what an R Markdown document can do; it keeps existing ones working.

◆ Prediction

Given that the last two releases both handled Pandoc 3.8 flag deprecations, the next is likely to track further Pandoc changes rather than add an output format.
