What is KACE?

KACE extends its PHP2SHELL fix to the SDA deployment appliance, six days after disclosure.

KACE has now patched the critical PHP2SHELL vulnerabilities across both appliances: SMA 15.1 and 15.0 on October 23, and the SDA 9.3 deployment appliance on October 27. SMA also gained official support for Windows 11 26H2 agents and patches, following KACE Cloud's 26H2 support a few days earlier.

What is Slack?

Slack now hosts any A2A agent without Slack-specific code.

Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.

KACE vs Slack: editorial side-by-side

K
KACE
COLLAB
5.0

KACE extends its PHP2SHELL fix to the SDA deployment appliance, six days after disclosure.

◆ Current state

KACE has now patched the critical PHP2SHELL vulnerabilities across both appliances: SMA 15.1 and 15.0 on October 23, and the SDA 9.3 deployment appliance on October 27. SMA also gained official support for Windows 11 26H2 agents and patches, following KACE Cloud's 26H2 support a few days earlier.

◆ Where it's heading

The changelog is dominated by security response and OS-version coverage, with both SMA branches patched in lockstep. Feature work is limited to agent reliability fixes. KACE behaves like a maintained endpoint-management line rather than one being redirected.

◆ Prediction

Expect November Patch Tuesday content and further cumulative patches on both SMA branches. The entries don't point to new feature work.

6.3

Slack now hosts any A2A agent without Slack-specific code.

◆ Current state

Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.

◆ Where it's heading

Slack is lowering the cost of putting outside agents in front of its users: first skills as code, then MCP pointers for coding agents, now a standard protocol in place of the Slack app model for agents. The platform is positioning itself as the place where agents built anywhere meet the people who use them.

◆ Prediction

Expect more A2A follow-ups, such as agents appearing in Slackbot or skills surfaces and richer Agent Card features, given how fast the agent releases have stacked up since October.
