Description
Agentfront mcp-from-openapi from 2.2.0 before 2.9.0 contains a server-side request forgery vulnerability that allows attackers to bypass the ssrf.blockedHosts denylist using trailing-dot hostnames. Attackers who control an OpenAPI spec URL or redirect target can append a root dot to a blocked hostname to fetch content from operator-blocked hosts.
