Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Fides (ethyca-fides) versions 2.11.0 through 2.18.0 are vulnerable to remote code execution through the custom integration upload feature. An attacker with the CONNECTOR_TEMPLATE_REGISTER scope, which is limited to highly privileged users, and with the allow_custom_connector_functions setting enabled can escape the sandbox and run arbitrary code as the webserver process owner, by default root. Upgrade to version 2.19.0 or later. Alternatively, leave allow_custom_connector_functions unset or set to False.
