Horizon Alert
Summary of the vulnerability and why it matters
Kibana, a data visualization tool, has a flaw in its Timelion visualizer that allows for arbitrary code execution. This vulnerability can be exploited by an attacker who can send a crafted request to the Timelion application. If successful, an attacker could execute commands with the same permissions as the Kibana process, potentially impacting the host system.
- Vulnerable component: Kibana Timelion visualizer
- Core weakness: Arbitrary code execution via crafted requests
- Main business impact: System compromise and command execution
Attack Path
How an attacker could exploit the issue
The Timelion visualizer in Kibana contains a flaw that allows for arbitrary code execution. An attacker can exploit this by sending a specially crafted request to the Timelion application. This action could enable an attacker to execute arbitrary commands, leveraging the same permissions as the Kibana process on the host system.
- Exposure condition: Network accessibility to Timelion.
- Attacker starting point: Unauthenticated access.
- Trigger and result: Malicious request leads to command execution.
Live Threat
Current exploitation, exposure, and threat context

This could allow an attacker to execute arbitrary commands on the host system with the same permissions as the Kibana process. Exploitation of this vulnerability carries significant business risk due to the potential for system compromise.
- Attacker skill level: Moderate
- Required access or conditions: Access to Timelion application
- Business risk or urgency: High
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
An arbitrary code execution vulnerability exists within the Timelion visualizer in affected versions of Kibana. This flaw could allow an attacker with access to the Timelion application to execute arbitrary commands on the host system, potentially impacting system integrity and data confidentiality. Organizations should prioritize addressing this vulnerability to mitigate business risk.
- Find Kibana instances that are exposed.
- Restrict Timelion access or isolate systems.
- Apply vendor updates and validate fixes.
