CVE-2026-108823 — Apache Kylin: Potential unauthenticated job metadata replacement

Exposure of Sensitive Information to an Unauthorized Actor during job manipulation in Apache Kylin. The impact is minor unless job services are exposed to public network, which is uncommon. This issue affects Apache Kylin: from 4.0.0 through 5.0.4. Users are recommended to upgrade to version 5.0.5, which fixes the issue.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • No scoring signals.

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Apache Software Foundation Kylin).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (info disclosure), errors and authentication anomalies.
