Summary

CVE-2025-25015 is a critical-severity Prototype Pollution (CWE-1321) vulnerability in Elastic Kibana. Its CVSS base score is 9.9 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 32% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Prototype pollution in Kibana enables arbitrary code execution when an attacker supplies a crafted file upload followed by specially constructed HTTP requests. The flaw affects Kibana versions 8.15.0 through 8.17.2 and is tracked as CWE-1321; the CVSS 3.1 score is 9.9.

In versions 8.15.0 to 8.17.0, any user holding the Viewer role can trigger the vulnerability. In 8.17.1 and 8.17.2 the attack surface is narrower, requiring a role that possesses the fleet-all, integrations-all, and actions:execute-advanced-connectors privileges. Successful exploitation yields full code execution on the Kibana host.

Elastic’s security advisory recommends immediate upgrade to Kibana 8.17.3 or 8.16.6, which contain the fix. The associated EPSS score remains low (current 0.0100, peak 0.0128) with no material increase after disclosure.
