CVE-2025-23195: Apache Ambari

High severity, CVSS 7.5. EPSS: 0.7% chance of exploitation in the next 30 days.

An XML External Entity (XXE) vulnerability exists in the Ambari/Oozie project, allowing an attacker to inject malicious XML entities. This vulnerability occurs due to insecure parsing of XML input using the `DocumentBuilderFactory` class without disabling external entity resolution. An attacker can exploit this vulnerability to read arbitrary files on the server or perform server-side request forgery (SSRF) attacks. The issue has been fixed in both Ambari 2.7.9 and the trunk branch.

Affected products

• Apache Ambari: before 2.7.9 (fixed in 2.7.9)
