CVE-2026-28672 · Severity: critical · CVSS 9.8 · Published 2026-08-10

Apache Ranger is an open-source framework that manages user access and permissions across Apache Hadoop clusters and other big data platforms. A command injection flaw in versions 0.6–2.8 allows unauthenticated attackers on the network to execute arbitrary operating system commands on servers running the affected software. This can lead to complete compromise of the system, including theft of sensitive data, unauthorized modifications, and service unavailability. No patch is currently available.

Technologies: Apache Ranger, org.apache.ranger:ranger (Maven). Vendors: Apache, Maven.

Technical details

This is a CWE-77 command injection vulnerability in Apache Ranger that fails to properly neutralize special elements in externally-controlled input before passing it to a downstream command execution handler. The vulnerability requires no authentication, has low attack complexity, and can be triggered remotely over the network without user interaction. An attacker can inject shell metacharacters or escape sequences into vulnerable input parameters to break out of the intended command context and execute arbitrary code with the privileges of the Ranger process. The impact includes full confidentiality, integrity, and availability compromise. As of the advisory publication (August 2026), no patched version exists.
