CVE-2026-34163

FastGPT · FastGPT

FastGPT, an AI Agent building platform, contains a security vulnerability that could lead to unauthorized access or manipulation of AI agent configurations.

Executive summary

A security vulnerability in the FastGPT AI platform could allow attackers to compromise AI agent workflows, leading to data leakage or the execution of unauthorized AI tasks.

Vulnerability

FastGPT is an AI Agent building platform that integrates with databases like MongoDB and Redis. The vulnerability likely involves a failure to properly secure agent configurations or API interactions, potentially allowing an attacker to intercept or modify the logic of deployed AI agents.

Business impact

As AI agents are increasingly used for automated business logic and data processing, a compromise in FastGPT could result in the leakage of proprietary prompts, API keys, or sensitive training data. The CVSS score of 7.7 reflects a high risk where an attacker could disrupt AI-driven business processes, leading to significant operational inaccuracies and loss of intellectual property.

Remediation

Immediate Action: Apply the latest security patches provided by the FastGPT maintainers and ensure that all associated database connections (MongoDB/Redis) use secure, encrypted channels.

Proactive Monitoring: Review AI agent execution logs for anomalous behavior and audit API access tokens for any signs of unauthorized usage or credential stuffing.

Compensating Controls: Implement strict network segmentation for the FastGPT environment and use robust authentication (such as OAuth2) to protect the agent-building interface.

Exploitation status

Public Exploit Available: false

Analyst recommendation

We recommend that organizations utilizing FastGPT for AI automation immediately review their deployment security and apply all available updates. Ensuring the integrity of AI workflows is critical for maintaining business continuity and protecting sensitive data processed by these agents.
