What is CommaFeed?

CommaFeed's security pass turns inward, from hostile feeds to hostile users

CommaFeed's 7.x line has become a sustained security pass, shipped one fix per patch release. The newest, 7.3.2, closes a cross-user data exposure: users could star or tag entries that were not theirs and then read them, filed as GHSA-prfv-88mm-5gpg. Behind it sit Host header injection on the password recovery endpoint with a new commafeed.password-recovery-public-base-url setting, local address blocking made secure by default alongside Google Reader API support in 7.3.0, and javascript: URL filtering moved to parse time.

What is Double?

Ask Double can now read and post in Microsoft Teams on an accountant's behalf.

Double is an accounting-practice platform built around QuickBooks Online, with the Ask Double assistant at its centre. The October 22 release connects Ask Double to Microsoft Teams, where it can read chats and channels and send messages as the user after confirmation, and lets it draft executive summaries and act on batches of tasks. Bookkeeping work continues alongside: customer-level and whole-P&L allocations, partial fixed-asset disposals and reminders for every open client request. The week before brought Ask Double to Xero and Consolidations in beta.

CommaFeed's security pass turns inward, from hostile feeds to hostile users

◆ Current state

CommaFeed's 7.x line has become a sustained security pass, shipped one fix per patch release. The newest, 7.3.2, closes a cross-user data exposure: users could star or tag entries that were not theirs and then read them, filed as GHSA-prfv-88mm-5gpg. Behind it sit Host header injection on the password recovery endpoint with a new commafeed.password-recovery-public-base-url setting, local address blocking made secure by default alongside Google Reader API support in 7.3.0, and javascript: URL filtering moved to parse time.

◆ Where it's heading

The earlier fixes in this run all closed paths where something from outside the instance was trusted too far — feed URLs reaching internal addresses, proxied images, javascript: links, a request header shaping an outbound email. 7.3.2 is a different shape: nothing external is involved, the attacker is a legitimate signed-in user, and the flaw is an ownership check missing on a write path that then leaks through a read path. That is the class of bug you find once you start auditing multi-tenancy rather than input handling, and it suggests the review has moved past the perimeter into the authorization model that the 7.0.0 multi-user rework put in place.

◆ Prediction

If the audit is now working through ownership checks rather than input validation, the other per-user write paths — subscription and category mutations, saved searches — are the likely next findings. The pattern of shipping each fix as its own patch release with a GHSA reference should continue rather than batching them.

Ask Double can now read and post in Microsoft Teams on an accountant's behalf.

◆ Current state

Double is an accounting-practice platform built around QuickBooks Online, with the Ask Double assistant at its centre. The October 22 release connects Ask Double to Microsoft Teams, where it can read chats and channels and send messages as the user after confirmation, and lets it draft executive summaries and act on batches of tasks. Bookkeeping work continues alongside: customer-level and whole-P&L allocations, partial fixed-asset disposals and reminders for every open client request. The week before brought Ask Double to Xero and Consolidations in beta.

◆ Where it's heading

Two tracks run in parallel: fuller QBO bookkeeping coverage and an AI layer that reaches across a firm's tools. Teams is the first connector in these entries where Ask Double writes outside the ledger, not just reads, with a confirmation step as the guardrail. The assistant is becoming the way staff operate Double in bulk, from tasks to reports.

◆ Prediction

Expect more write-capable connectors with the same confirm-before-send pattern, and Ask Double on Xero gaining write actions after its read-only beta.
