What is Apache CloudStack?

CloudStack's feed shows two LTS branches maintained in parallel and little else

The visible activity on Apache CloudStack is branch maintenance across two long-term-support lines, 4.20 and 4.22. The newest tag, 4.20.3.1, carries no release notes at all — just a line stating it was tagged on a fixes branch. The most informative recent entry remains 4.22.0.1, a security release fixing seven CVEs, several of them access-control failures around backups.

What is Icinga?

Icinga 2 is fixing the same API permission holes across every supported branch.

Icinga 2 ships security fixes as simultaneous releases across its 2.14, 2.15, and 2.16 branches, and has now done so twice in five weeks. The 18 August pair - v2.16.5 and v2.15.6, tagged 25 seconds apart - closes an events/* permission bypass on /v1/events and a memory-exhaustion path where a node could crash another using the 1 GB message limit, now capped at 16 MiB for messages from lower in the hierarchy. v2.16.5 additionally repairs an IcingaDB regression introduced in v2.16.0.

CloudStack's feed shows two LTS branches maintained in parallel and little else

◆ Current state

The visible activity on Apache CloudStack is branch maintenance across two long-term-support lines, 4.20 and 4.22. The newest tag, 4.20.3.1, carries no release notes at all — just a line stating it was tagged on a fixes branch. The most informative recent entry remains 4.22.0.1, a security release fixing seven CVEs, several of them access-control failures around backups.

◆ Where it's heading

This feed publishes tags, not changelogs: every maintenance release points at external documentation rather than listing what changed, so direction has to be inferred from version numbers and the occasional security advisory. What can be read from it is a steady dual-branch cadence, with 4.20 and 4.22 receiving parallel maintenance and 4.22 carrying the newer feature work. The one substantive disclosure in this window, the CVE batch, clustered around backup and template permissions.

◆ Prediction

The dual-branch maintenance pattern should continue, though the feed itself will not reveal feature direction unless a security advisory forces detail into it.

Icinga 2 is fixing the same API permission holes across every supported branch.

◆ Current state

Icinga 2 ships security fixes as simultaneous releases across its 2.14, 2.15, and 2.16 branches, and has now done so twice in five weeks. The 18 August pair - v2.16.5 and v2.15.6, tagged 25 seconds apart - closes an events/* permission bypass on /v1/events and a memory-exhaustion path where a node could crash another using the 1 GB message limit, now capped at 16 MiB for messages from lower in the hierarchy. v2.16.5 additionally repairs an IcingaDB regression introduced in v2.16.0.

◆ Where it's heading

The recurring theme is that the API's filter and permission model was more permissive than intended. July's critical release introduced a filter-expression permission so DSL filters in API queries can be restricted per user, with enforcement deliberately deferred to v2.17; August's pair fixes filter expressions on /v1/events not being permission-checked at all. Cluster message handling is being tightened in parallel. The project is clearly working through an audit of the API surface, and it is backporting every finding rather than pushing users onto the newest branch.

◆ Prediction

Enforcement of the filter-expression permission is already scheduled for v2.17, so that release should be the one where the opt-in restrictions become mandatory - expect more backported API permission fixes across all three branches before it lands.
