CVE-2026-22219

CVSS v4.0
8.3
VectorAV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N
Name of the Vulnerable Software and Affected Versions Chainlit versions prior to 2.9.4
Description 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. Server-Side Request Forgery (SSRF) occurs when a server fetches a remote resource without properly validating the user-supplied URL, potentially exposing internal services or sensitive data. On AWS clouds with older settings (IMDSv1), this could potentially lead to the theft of login credentials and full system takeover.
Recommendations Versions prior to 2.9.4 should be updated to version 2.9.4 or later.
