CVE-2024-38363
About
Airbyte is a data integration platform for ELT pipelines. Airbyte connection builder docker image is vulnerable to RCE via SSTI which allows an authenticated remote attacker to execute arbitrary code on the server as the web server user. The connection builder is used to create and test new connectors. Sensitive information, such as credentials, could be exposed if a user tested a new connector on a compromised instance. The connection builder does not have access to any data processes. This vulnerability is fixed in 0.62.2.
Rainforest analyst review
Airbyte's connection-builder image can be pushed into server-side template injection, and from there an authenticated remote user runs arbitrary code as the web-server user. The connection builder exists to create and test new connectors, so the injection rides in through exactly the input it's meant to accept, turning a development feature into a code-execution surface.
The advisory is refreshingly precise about scope: exploitation needs authentication and the attack is rated difficult, and while the builder can't touch data-processing flows, credentials tested on a compromised instance could be exposed. That frames this as an authenticated-user or insider risk to the build environment and its secrets, not an unauthenticated internet takeover, which tempers the urgency below a naive reading of 8.5.
We treat this as protecting a sensitive internal tool. The connection builder shouldn't be broadly reachable, so our first check is who can authenticate to it and whether it's exposed beyond the team that needs it. Given the credential-exposure angle, we'd also make sure connectors under development are tested with throwaway rather than production secrets, so a compromise of the builder doesn't hand over real keys.
