Apache Kylin vulnerable to remote code execution
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Description
Kylin's cube designer function has a command injection vulnerability when overwriting system parameters in the configuration overwrites menu. RCE can be implemented by closing the single quotation marks around the parameter value of “-- conf=” to inject any operating system command into the command line parameters. This vulnerability affects Kylin 2 version 2.6.5 and earlier, Kylin 3 version 3.1.2 and earlier, and Kylin 4 version 4.0.1 and earlier.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.kylin:kylin-core-common, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.apache.kylin:kylin-core-common to 4.0.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-ppxx-m926-g569 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-ppxx-m926-g569 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-ppxx-m926-g569. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-ppxx-m926-g569 in your dependencies?
O3 Security finds GHSA-ppxx-m926-g569 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
