CVE-2024-48944Network attack vector

Internal data disclosure via Base64-decoded diagnosis host

Published Mar 27, 2025 · Updated May 8, 2025

SSRF in Apache Kylin 5.0.0 through 5.0.1 allows remote authenticated users to read data from an internal diagnostic API. NBasicController decodes a caller-supplied host from reversible Base64 and uses it as the destination for cross-host diagnosis requests. Administrative access to one Kylin server and an exposed /kylin/api/xxx/diag endpoint on another internal host are required.
