AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-22219 is a Server-Side Request Forgery (SSRF) vulnerability in Chainlit versions prior to 2.9.4 when using the SQLAlchemy data layer backend. An authenticated user can provide a URL in an Element during the /project/element update flow. The server then makes an HTTP GET request to this user-controlled URL. This allows an attacker to make arbitrary HTTP requests from the Chainlit server to internal network services or cloud metadata endpoints and capture the responses. [1]
How can this vulnerability impact me? :
This vulnerability can allow an attacker to make unauthorized HTTP requests from the Chainlit server to internal or cloud services that are normally inaccessible externally. The attacker can retrieve sensitive information from internal network services or cloud metadata endpoints and store this data via the configured storage provider. This can lead to data exposure and compromise of internal systems. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection involves monitoring for unusual outbound HTTP GET requests originating from the Chainlit server, especially to internal network services or cloud metadata endpoints. Since the vulnerability is triggered via the /project/element update flow by an authenticated client supplying a user-controlled URL, reviewing logs for such requests or suspicious URL parameters in requests to /project/element can help. Specific commands are not provided in the resources. [1]
What immediate steps should I take to mitigate this vulnerability?
The immediate mitigation step is to upgrade Chainlit to version 2.9.4 or later, where this SSRF vulnerability has been fixed. Additionally, restricting authenticated user permissions and monitoring outbound HTTP requests from the server can help reduce risk until the upgrade is applied. [1]
