CVE-2026-108583 PUBLISHED

zotero-mcp 0.10.0 through 0.14.1 SSRF via zotero_add_by_url Tool

Assigner: VulnCheck
Reserved: 10.10.2026 Published: 10.10.2026 Updated: 10.10.2026

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