AI Analysis
Technical Summary
CVE-2026-65948 identifies a vulnerability in Apache Ranger's UnixAuth authentication mechanism where there is improper restriction of excessive authentication attempts (CWE-307). This lack of brute-force protection affects Apache Ranger versions up to and including 2.8.0. The vendor recommends upgrading to version 2.9.0 to address this issue. UnixAuth is noted as not recommended for production deployments.
Potential Impact
Without brute-force protection, an attacker could attempt numerous authentication attempts without being throttled or blocked, potentially increasing the risk of unauthorized access if weak credentials are used. However, since UnixAuth is not recommended for production, the practical impact may be limited to non-production or misconfigured environments.
Mitigation Recommendations
Users should upgrade Apache Ranger to version 2.9.0 or later, where this vulnerability is fixed. Additionally, avoid using UnixAuth in production environments as it is not recommended by the vendor.
