Splunk patched a critical remote code execution flaw in its MCP Server

Reported August 20, 2026 · 1 source

What happened

Splunk patched a remote code execution flaw rated CVSS 9.1 in its MCP Server, along with nine other vulnerabilities in its AI Toolkit.

Why it matters

An MCP server sits between an agent and everything that server can reach, so remote code execution there compromises the integration rather than just one endpoint.
