CVE-2026-7178

Estado: AnalizadaMedia (5.5)—

A weakness has been identified in ChatGPTNextWeb NextChat up to 2.16.1. This affects the function storeUrl of the file app/api/artifacts/route.ts of the component Artifacts Endpoint. This manipulation of the argument ID causes server-side request forgery. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
