CVE-2026-22219 (GCVE-0-2026-22219)
Vulnerability from cvelistv5 – Published: 2026-01-19 23:15 – Updated: 2026-03-05 01:30
VLAI
Title
Chainlit < 2.9.4 SQLAlchemy Data Layer SSRF via /project/element
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.

CVE-2026-22218 (GCVE-0-2026-22218)
Vulnerability from cvelistv5 – Published: 2026-01-19 23:14 – Updated: 2026-03-05 01:30

Title
Chainlit < 2.9.4 Arbitrary File Read via /project/element
Summary
Chainlit versions prior to 2.9.4 contain an arbitrary file read vulnerability in the /project/element update flow. An authenticated client can send a custom Element with a user-controlled path value, causing the server to copy the referenced file into the attacker’s session. The resulting element identifier (chainlitKey) can then be used to retrieve the file contents via /project/file/<chainlitKey>, allowing disclosure of any file readable by the Chainlit service.
