What is containerd?

containerd ships four security advisories and a tighter default seccomp across four branches

containerd maintains five release branches: 1.7, 2.0, 2.2, 2.3 LTS and 2.4. On October 13 it patched 2.0 through 2.4 for CVE-2026-95839 and three GHSA advisories, three weeks after the CVE-2026-53493 round. The fixes harden inputs an attacker can control: container log symlinks are no longer followed, image references containing '..' are rejected, ID-mapping labels are filtered from image annotations, and the default seccomp profile now allowlists socket domains.

What is Sanity?

Sanity's MCP server now advertises itself to agents through a server card and llms.txt.

Sanity shipped three MCP server releases in two days. 2.44.0 makes the server discoverable through a /.well-known server card, an HTML or markdown landing page, robots.txt and llms.txt, and cuts CPU per request. 2.43.0 adds an undeploy_schema tool and deprecates workspaceName for schema selection. 2.42.2 fixes validation against deployed schemas and refuses patches that would change a document's _type.

containerd vs Sanity: editorial side-by-side

C5.0

containerd ships four security advisories and a tighter default seccomp across four branches

◆ Current state

containerd maintains five release branches: 1.7, 2.0, 2.2, 2.3 LTS and 2.4. On October 13 it patched 2.0 through 2.4 for CVE-2026-95839 and three GHSA advisories, three weeks after the CVE-2026-53493 round. The fixes harden inputs an attacker can control: container log symlinks are no longer followed, image references containing '..' are rejected, ID-mapping labels are filtered from image annotations, and the default seccomp profile now allowlists socket domains.

◆ Where it's heading

Two coordinated multi-branch security rounds in three weeks show maintenance shifting toward closing untrusted-input paths in image references, annotations and log files. The seccomp allowlist is the one change that can alter runtime behavior, since workloads opening uncommon socket families may now be blocked by default. Feature work stays on 2.4, whose patch line is also fixing pull-time memory growth.

◆ Prediction

Expect a 1.7 patch with whichever of these fixes apply there, since every other branch moved the same day. The entries don't show whether the seccomp socket allowlist will need follow-up exceptions.

5.0

Sanity's MCP server now advertises itself to agents through a server card and llms.txt.

◆ Current state

Sanity shipped three MCP server releases in two days. 2.44.0 makes the server discoverable through a /.well-known server card, an HTML or markdown landing page, robots.txt and llms.txt, and cuts CPU per request. 2.43.0 adds an undeploy_schema tool and deprecates workspaceName for schema selection. 2.42.2 fixes validation against deployed schemas and refuses patches that would change a document's _type.

◆ Where it's heading

The MCP server is becoming the main way agents read and write Sanity content, and the work has shifted from adding tools to making it safe and findable: guarded patches, accurate safety annotations, full schema lifecycle and discovery metadata. Studio and Manage continue alongside it with speed work and admin features for larger organizations.

◆ Prediction

Expect workspaceName to be removed after the migration period, and more guardrails on write tools such as patch_documents.
