What is Bludit?

A flat-file CMS with a long CVE history just wired its API up for MCP.

Bludit ships every few weeks, and almost every release carries a security fix: an authentication bypass and arbitrary file upload in 3.18.4, an authenticated RCE via file upload plus .htaccess bypass in 3.20.0, a path traversal in the API files endpoint in 3.21.0, and session invalidation for disabled users in 3.22.0. Around that, the work is editor and dashboard maintenance, theme additions and a plugin hook for injecting editor toolbar buttons.

What is Umbraco CMS?

Umbraco 19 reaches its first release candidate on .NET 11 GA.

Umbraco 19.0.0-rc1 arrived on 12 November, two weeks after the first beta, and moves the release onto .NET 11 GA. The beta brought reusable Library content to every block editor and search into core; rc1 adds Entra ID SQL authentication, action groups in menus, an API switch that lets code block schema changes per environment, and a fix that admits one request per process into the content write path on load-balanced sites. The 18.3 and 17.8 candidates are still on rc2, which resolved seven security advisories.

0.0

A flat-file CMS with a long CVE history just wired its API up for MCP.

◆ Current state

Bludit ships every few weeks, and almost every release carries a security fix: an authentication bypass and arbitrary file upload in 3.18.4, an authenticated RCE via file upload plus .htaccess bypass in 3.20.0, a path traversal in the API files endpoint in 3.21.0, and session invalidation for disabled users in 3.22.0. Around that, the work is editor and dashboard maintenance, theme additions and a plugin hook for injecting editor toolbar buttons.

◆ Where it's heading

Two threads run in parallel. One is a sustained security cleanup, largely driven by external reports and handled release by release. The other is a quiet repositioning of the API: 3.22.0 improved it specifically to support MCP, which points a file-based CMS at agent-driven authoring. The plugin hook work in 3.20.0 fits the same pattern of opening the editor to programmatic control.

◆ Prediction

Expect the MCP-facing API work to continue — the initial support arrived as API improvements rather than a documented server, which is the piece still missing.

6.3

Umbraco 19 reaches its first release candidate on .NET 11 GA.

◆ Current state

Umbraco 19.0.0-rc1 arrived on 12 November, two weeks after the first beta, and moves the release onto .NET 11 GA. The beta brought reusable Library content to every block editor and search into core; rc1 adds Entra ID SQL authentication, action groups in menus, an API switch that lets code block schema changes per environment, and a fix that admits one request per process into the content write path on load-balanced sites. The 18.3 and 17.8 candidates are still on rc2, which resolved seven security advisories.

◆ Where it's heading

The 19 cycle is moving quickly from beta to candidate, and rc1 is about hardening rather than new editor features: dependencies on GA, environment-level permissions and load-balancing performance. The 17 and 18 lines are kept in step on security fixes while 19 matures.

◆ Prediction

Expect 18.3 and 17.8 to go stable, followed by further 19 release candidates and a 19.0.0 stable release built on .NET 11.
