What is CVE-2026-108583?
CVE-2026-108583 is a low-severity server-side request forgery vulnerability in 54yyyu zotero-mcp, published on 10 Oct 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official 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.
