- 5.4MediumNov 2, 2026Chainlit SSRFCVE-2026-120492Chainlit 2.12.0 contains a server-side request forgery vulnerability that allows unauthenticated attackers to bypass path-scoped MCP allowed_urls entries because validate_mcp_url does not reject the semicolon character. Attackers can submit MCP URLs with '..;' segments to the /mcp endpoint, causing requests to paths outside the operator's grant on origins that strip semicolon path parameters.
- 8.2HighSep 9, 2026chainlit Path traversal / file handlingCVE-2026-86099Chainlit through 2.12.0 fails to validate the client-supplied socket.io sessionId parameter, allowing unauthenticated attackers to traverse filesystem paths by injecting absolute or relative path sequences. Attackers can craft malicious sessionId values that escape the upload directory and recursively delete arbitrary directories accessible to the service process.
- 7.7HighJan 20, 2026chainlit SSRFCVE-2026-22219Chainlit 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 s5.2% likely
- 6.5MediumJan 20, 2026chainlit Path traversal / file handlingCVE-2026-22218Chainlit 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.9.7% likely
