CVE-2023-39264Network attack vector

Authenticated internal trace disclosure via error responses

Published Sep 6, 2023 · Updated Sep 26, 2024

Information disclosure in Apache Superset 2.1.0 and earlier allows remote authenticated users to read internal traces via REST API errors. The default SHOW_STACKTRACE setting is true, causing REST error handlers such as get_error_msg to serialize Python tracebacks into responses. A low-privileged account must trigger an endpoint error; the exposed trace reveals internal code paths and diagnostic details, with no direct write or service-interruption capability reported.
