FKIE_CVE-2026-22219

Vulnerability from fkie_nvd - Published: 2026-01-20 00:15 - Updated: 2026-02-02 20:56
Severity ?
7.7 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N
Summary
Chainlit versions prior to 2.9.4 contain a server-side request forgery (SSRF) vulnerability in the /project/element update flow when configured with the SQLAlchemy data layer backend. An authenticated client can provide a user-controlled url value in an Element, which is fetched by the SQLAlchemy element creation logic using an outbound HTTP GET request. This allows an attacker to make arbitrary HTTP requests from the Chainlit server to internal network services or cloud metadata endpoints and store the retrieved responses via the configured storage provider.

Un cliente autenticado puede proporcionar un valor de URL controlado por el usuario en un Element, que es recuperado por la l\u00f3gica de creaci\u00f3n de elementos de SQLAlchemy utilizando una petici\u00f3n HTTP GET saliente. Esto permite a un atacante realizar peticiones HTTP arbitrarias desde el servidor de Chainlit a servicios de red internos o puntos finales de metadatos en la nube y almacenar las respuestas recuperadas a trav\u00e9s del proveedor de almacenamiento configurado."
