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 Excalidraw?

Excalidraw's package went ESM-only in 0.18 — a big release, then 16 months of silence on this feed.

This feed tracks the embeddable @excalidraw/excalidraw package rather than the hosted app, so every entry is a library release aimed at developers integrating the canvas. Version 0.18.0 in March 2025 was the large one: command palette, multiplayer undo and redo, flowcharts, elbow arrows, scene search, image cropping, element linking, CJK fonts, and a move from UMD to ES modules that broke existing consumers. Earlier releases are smaller, mostly programmatic API surface and rendering fixes. Nothing has been captured since.

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.

Excalidraw logo0.0

Excalidraw's package went ESM-only in 0.18 — a big release, then 16 months of silence on this feed.

◆ Current state

This feed tracks the embeddable @excalidraw/excalidraw package rather than the hosted app, so every entry is a library release aimed at developers integrating the canvas. Version 0.18.0 in March 2025 was the large one: command palette, multiplayer undo and redo, flowcharts, elbow arrows, scene search, image cropping, element linking, CJK fonts, and a move from UMD to ES modules that broke existing consumers. Earlier releases are smaller, mostly programmatic API surface and rendering fixes. Nothing has been captured since.

◆ Where it's heading

The package's direction has been to expose more of the editor to host applications — API subscribers, programmatic element creation, viewport control, sidebar tabs — so Excalidraw can be embedded as a component rather than only used as a site. The ESM transition fits that: tree-shakable output matters to the teams shipping it inside their own products. With no releases captured in over a year, this source no longer says anything about current activity, which more likely reflects the crawl target than the project.

◆ Prediction

Insufficient data for a forward call from this feed: the last captured release predates the window by more than a year, so any prediction would be about the package's dormancy rather than Excalidraw's actual roadmap.
