CVE-2025-27600Network attack vector

Internal data disclosure via unchecked crawl destination

Published Mar 6, 2025 · Updated Mar 6, 2025

SSRF in the web-crawling plug-in in Labring FastGPT before 4.9.0 allows remote attackers to read internal network data. The plug-in accepts an attacker-supplied intranet IP as a crawl target and directs the FastGPT server to fetch it without verifying that the destination is internal. Network access to the plug-in is sufficient; returned internal responses can disclose private data reachable from the server.
