CommaFeed vs Nextcloud: at a glance
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 Nextcloud?
Nextcloud ships three patch lines in a day as 35.0.2 adds webhook metadata and a report API.
Nextcloud released 35.0.2, 34.0.5 and 33.0.10 on the same day, a month after the 35.0.0 major that swapped OnlyOffice for Euro-Office and added FrankenPHP support. The backports share a security-flavored core: a CSRF token on the share-accept endpoint, upload checks against session and share tokens, and logs that no longer leak sensitive data. 35.0.2 also adds richer node-webhook metadata, webhook-compatible comment events and an API for system-report sections.

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.

Nextcloud ships three patch lines in a day as 35.0.2 adds webhook metadata and a report API.
◆ Current state
Nextcloud released 35.0.2, 34.0.5 and 33.0.10 on the same day, a month after the 35.0.0 major that swapped OnlyOffice for Euro-Office and added FrankenPHP support. The backports share a security-flavored core: a CSRF token on the share-accept endpoint, upload checks against session and share tokens, and logs that no longer leak sensitive data. 35.0.2 also adds richer node-webhook metadata, webhook-compatible comment events and an API for system-report sections.
◆ Where it's heading
The patch stream is still dominated by sharing permissions, resharer caps and encryption cache fixes, now applied across three supported branches at once. The small additions in 35.0.2, webhooks and the 'Unified Sharing Legacy Sync' groundwork, point to sharing being rebuilt under the hood and to more automation hooks for integrators. The 35 line is absorbing regressions from the major at a steady monthly pace.
◆ Prediction
Expect a 35.0.3 within a month continuing sharing and encryption fixes, with more of the unified-sharing work surfacing; the entries do not say when that rework becomes user-visible.
