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 Outline?

Outline gave AI assistants write access to the wiki, then spent months on the human side.

The April MCP expansion is the structural change in this window: assistants can patch documents, move and delete documents and collections, work with attachments, and create and resolve inline comments. Everything since has been human-facing and smaller — request-access flows for documents members cannot open, email subscriptions to publicly shared documents with change summaries, task list and checkbox handling in the editor, and profile cards on avatar hover.

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.

Outline gave AI assistants write access to the wiki, then spent months on the human side.

◆ Current state

The April MCP expansion is the structural change in this window: assistants can patch documents, move and delete documents and collections, work with attachments, and create and resolve inline comments. Everything since has been human-facing and smaller — request-access flows for documents members cannot open, email subscriptions to publicly shared documents with change summaries, task list and checkbox handling in the editor, and profile cards on avatar hover.

◆ Where it's heading

Two audiences are being served in sequence. The MCP work moved assistants from reading the knowledge base to editing it, including the collection structure itself. The releases after it close ordinary gaps in how people find, follow and get into documents — which is what a wiki needs before more of its edits arrive from automation. Release cadence is roughly monthly with entries that describe outcomes rather than changelogs.

◆ Prediction

Expect the human-facing polish to continue at its current pace, with any next structural move likely extending the MCP surface further into permissions and collection management, since that is where the existing tools stop.
