NVD Description

Note: Versions mentioned in the description apply only to the upstream kibana-9.2-config package and not the kibana-9.2-config package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Anthropic's MCP TypeScript SDK versions up to and including 1.25.1 contain a regular expression denial of service (ReDoS) vulnerability in the UriTemplate class when processing RFC 6570 exploded array patterns. The dynamically generated regular expression used during URI matching contains nested quantifiers that can trigger catastrophic backtracking on specially crafted inputs, resulting in excessive CPU consumption. An attacker can exploit this by supplying a malicious URI that causes the Node.js process to become unresponsive, leading to a denial of service.
