CVE-2026-26075Network attack vector

Internal service access via incomplete address filtering

Published Feb 12, 2026 · Updated Feb 12, 2026

SSRF in FastGPT before 4.14.7 allows remote attackers to reach internal services through server-side workflow requests. Web acquisition and HTTP nodes accepted destinations without fully rejecting IPv6, localhost, and DNS-resolved internal addresses before issuing requests. Exposure requires an attacker-influenced URL to reach one of these nodes; successful requests can read from or invoke services accessible from the FastGPT server.
