Detailsinfo

A vulnerability was found in labring FastGPT up to 4.14.9.5. It has been rated as critical. This issue affects an unknown function of the component Password Change Endpoint. The manipulation with an unknown input leads to a data query logic injection vulnerability. Using CWE to declare the problem leads to CWE-943. The product generates a query intended to access or manipulate data in a data store such as a database, but it does not neutralize or incorrectly neutralizes special elements that can modify the intended logic of the query. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

FastGPT is an AI Agent building platform. In versions prior to 4.14.9.5, the password change endpoint is vulnerable to NoSQL injection. An authenticated attacker can bypass the "old password" verification by injecting MongoDB query operators. This allows an attacker who has gained a low-privileged session to change the password of their account (or others if combined with ID manipulation) without knowing the current one, leading to full account takeover and persistence. This issue has been fixed in version 4.14.9.5.

It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2026-40352 since 04/11/2026. The exploitation is known to be easy. The attack may be initiated remotely. The technical details are unknown and an exploit is not publicly available.
