CVE-2026-44285Public exploitNetwork attack vector

Authenticated internal data disclosure via unchecked URL fetch

Published May 29, 2026 · Updated May 29, 2026

SSRF in Labring FastGPT before 4.15.0-beta1 allows remote authenticated users to read internal HTTP services through dataset preview. The externalFile path passes the user-controlled sourceId to readFileRawTextByUrl, which sends an axios GET without calling isInternalAddress. A valid session or API token and dataset access are required; returned text chunks expose readable internal responses, including metadata.
