CVE-2026-64959: Apache Kylin: Missing authentication on certain cache API endpoints

Noroxi assessment

Priority: Monitor (action score 39/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.68% (FIRST EPSS); higher than 52.1% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: Apache Software Foundation Apache Kylin 5.0.5.

Low priority for now. Upgrade to Apache Software Foundation Apache Kylin 5.0.5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), Missing Authentication for Critical Function vulnerability in Apache Kylin. Impact most to the kylin services that are directly exposed to public network, which is not common. In-house kylin deployments are mostly not impacted. This issue affects Apache Kylin: from 5 through 5.0.4. Certain backend cache API misses required authentication and can cause execution of injected SQL. Users are recommended to upgrade to version 5.0.5, which fixes the issue.
