zotero-mcp 0.10.0 through 0.14.1 contains a server-side request forgery vulnerability that allows attackers to reach internal services because fetchembeddedmetadata fetches URLs without destination validation. Attackers can steer the agent via prompt injection into calling zoteroaddbyurl, causing requests to loopback, private, or link-local hosts directly or via redirects, leaking citation meta-tags and error details.
