CVE-2026-19770Public exploit

Internal HTTP resource disclosure via unchecked report URL

Published Aug 14, 2026 · Updated Aug 14, 2026

SSRF in FeedMob fm-mcp-servers 0.0.3 allows local users to read internal HTTP resources through a crafted Smadex report URL. The get_smadex_report handler accepts downloadUrl as an unrestricted string, passes it to downloadReport, and fetches the destination without host, address-range, port, or redirect validation. A low-privilege user able to invoke the local stdio MCP tool can originate requests from the server context and receive the response body.
