CVE-2026-108583 Details
Description
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.
A server-side request forgery (SSRF) vulnerability has been identified in Zotero-MCP versions 0.10.0 through 0.14.1. The issue arises in the 'zotero_add_by_url' tool, which imports metadata from user-supplied URLs. The vulnerability allows attackers to access internal services by injecting prompts that manipulate the tool into fetching URLs without proper validation. This oversight enables requests to loopback, private, or link-local hosts, either directly or through redirects, potentially leaking citation metadata and error information.
The vulnerability has been fixed in version 0.14.2. Users should update to this version.
