CVE-2026-65942: CWE-297 Improper Validation of Certificate with Host Mismatch in Apache Software Foundation Apache Ranger
TLS hostname verification issue in Apache Ranger Client Code in versions <= 2.8.0. Users are recommended to upgrade to version 2.9.0, which fixes this issue.
AI Analysis
Technical Summary
This vulnerability (CWE-297) affects Apache Ranger Client Code in versions <= 2.8.0, where TLS hostname verification is improperly performed. This flaw means that the client may accept TLS certificates even if the hostname in the certificate does not match the intended server hostname, weakening the security guarantees of TLS. The issue is resolved in version 2.9.0 of Apache Ranger.
Potential Impact
The improper validation of TLS certificates with hostname mismatches can lead to man-in-the-middle attacks or interception of secure communications if an attacker can present a certificate with a mismatched hostname. This undermines the confidentiality and integrity of data transmitted between the client and server.
Mitigation Recommendations
Users are recommended to upgrade Apache Ranger to version 2.9.0 or later, where this TLS hostname verification issue is fixed. No other mitigation or temporary workaround is provided in the available data.
