CVE-2026-28672 -- CVSS 9.8 Vulnerability Briefing

CVE-2026-28672 | CVSS 9.8 (Critical) | Exploit: No known exploit

What Is It

CVE-2026-28672 is a command injection vulnerability affecting Apache Ranger versions 0.6 through 2.8, in which insufficient neutralization of command-special elements may allow attacker-controlled input to be interpreted by an underlying command execution mechanism.

Technical Detail

The vulnerability is classified as CWE-78, Improper Neutralization of Special Elements used in a Command. An attacker who can reach the vulnerable input path may be able to inject operating system commands that execute in the security context of the affected Apache Ranger component. Successful exploitation could result in remote code execution, data access, service disruption, or further compromise of systems accessible to the Ranger service account; the precise vulnerable input path and prerequisites are not confirmed in the available data.

Exploitation Status

No known exploit has been reported, and CVE-2026-28672 is not listed in CISA's Known Exploited Vulnerabilities Catalog as of August 17, 2026. Public proof-of-concept or operational exploit availability is not confirmed.

Who Is Targeting This

No specific threat actor attribution at this time.

What To Do

Prioritize remediation of Apache Ranger deployments running versions 0.6 through 2.8. Apply the vendor-provided fixed release or security update when available, and review Apache Ranger configuration and deployment guidance for any interim mitigations. Until remediation is complete, restrict access to Ranger administrative and management interfaces, limit network exposure to trusted administrators and systems, run Ranger services with least-privileged accounts, and monitor Ranger hosts and associated logs for unexpected process execution, shell invocation, or anomalous child processes. No specific detection indicators or supported workaround are confirmed in the available data.
