CVE-2026-94051Public exploitNetwork attack vector

Internal service access via unvalidated PDF URL

Published Sep 20, 2026 · Updated Sep 20, 2026

SSRF in 0717376 Cowork Bench allows remote authenticated users to make the pdf-tools-mcp server access restricted network services. The get_pdf_info tool passes attacker-controlled pdf_file_path data through resolve_path to requests.head and requests.get with redirects enabled, without validating hosts, ports, IP addresses, or redirect targets. Access to the MCP interface is required; the resulting server-originated requests can reach loopback, internal, or metadata endpoints before PDF validation fails.
