What is Cursor?

Cursor's Agent SDK turns custom agents into code projects you can test, then deploy anywhere.

Cursor has grown from an editor into a delivery platform: Projects coordinates cloud agents, Origin hosts repos with a 20+ app marketplace, Rollouts watches deploys, and the Environments API scripts agent sandboxes. On October 20 the Agent SDK went GA. An agent is now a folder with a prompt, typed tools, skills, MCP connections and channels, tested with evals and deployed either to Cursor or to the team's own infrastructure.

What is Portainer?

Portainer 2.45.3 drops trust in eMudhra certificates and scopes kubeconfig tokens per environment.

Portainer 2.45.3 LTS stops trusting eMudhra emSign certificates after the compromise of eight intermediates, which can break SSO, LDAPS, registry and Git connections that use them. It also limits downloaded kubeconfig tokens to one environment's Kubernetes proxy, blocks a volumes_from route around hidden bind mounts, and patches a batch of critical Go and Helm CVEs.

7.5

Cursor's Agent SDK turns custom agents into code projects you can test, then deploy anywhere.

◆ Current state

Cursor has grown from an editor into a delivery platform: Projects coordinates cloud agents, Origin hosts repos with a 20+ app marketplace, Rollouts watches deploys, and the Environments API scripts agent sandboxes. On October 20 the Agent SDK went GA. An agent is now a folder with a prompt, typed tools, skills, MCP connections and channels, tested with evals and deployed either to Cursor or to the team's own infrastructure.

◆ Where it's heading

The last month has been about opening Cursor's agent stack to outside code: partner apps write into Origin, the Environments API exposes sandboxes, and the Agent SDK lets teams build their own bots on the same runtime. Agents that wake on PR, CI, Slack, webhook and cron events push Cursor past the IDE into always-on team automation. Cursor is selling the agent runtime itself, not just its own agents.

◆ Prediction

Expect more starter templates and SDK-built agents to appear in the app marketplace, and tighter links between SDK agents and Projects or Rollouts. Whether self-hosted deploys get the same dashboard tooling as Cursor-hosted ones is not yet clear from the entries.

5.0

Portainer 2.45.3 drops trust in eMudhra certificates and scopes kubeconfig tokens per environment.

◆ Current state

Portainer 2.45.3 LTS stops trusting eMudhra emSign certificates after the compromise of eight intermediates, which can break SSO, LDAPS, registry and Git connections that use them. It also limits downloaded kubeconfig tokens to one environment's Kubernetes proxy, blocks a volumes_from route around hidden bind mounts, and patches a batch of critical Go and Helm CVEs.

◆ Where it's heading

Every release in the 2.45 line has closed another way for non-admins or tokens to reach beyond their scope: the Docker proxy bypass, SSRF, bind-mount escapes, and now kubeconfig tokens. Native Kubernetes APIs from 2.45.0 make that tightening possible, and GitOps polling keeps getting reliability fixes alongside.

◆ Prediction

Expect a 2.39 LTS backport of the eMudhra and kubeconfig changes, and further token and permission scoping in the next 2.45 patch.
