CVE-2026-108771
UnknownSummary
A vulnerability in Apache Kylin involving missing authentication for in-house broadcast and polymorphic deserialization. It affects versions 4.0.0 through 5.0.4 and impacts mainly services directly exposed to the public network.
Risk Assessment
The risk is high for Kylin services exposed to the internet, where missing authentication and deserialization may enable remote code execution; in-house deployments are mostly not impacted.
Recommendation
Upgrade Apache Kylin to version 5.0.5 and restrict direct public network access to Kylin services.
