01

Who is affected

FastGPT platform, specifically versions earlier than 4.14.9.5. Developers and teams using FastGPT’s HTTP tools testing endpoint are affected.

02

Real-world impact

An attacker can send arbitrary HTTP requests from the FastGPT server to any target, potentially accessing internal resources, exfiltrating data, or performing malicious actions without needing credentials.

03

Why this severity

The CVSS score of 10 reflects that the flaw is exploitable over the network (AV:N), requires no authentication (PR:N) or user interaction (UI:N), and changes the system’s security scope (S:C). It grants high confidentiality and integrity impact, while availability impact is low, leading to the maximum score.
