How the CVE Works
CVE-2025-53689 is a Blind XML External Entity (XXE) vulnerability in Apache Jackrabbit’s `jackrabbit-spi-commons` and `jackrabbit-core` components. The flaw arises due to improper validation of XML input when processing document types, allowing attackers to exploit unsecured DocumentBuilder instances. By crafting malicious XML payloads, an attacker can force the parser to read sensitive files, initiate Server-Side Request Forgery (SSRF), or exfiltrate internal data. The vulnerability affects versions before 2.20.17 (Java 8), 2.22.1 (Java 11), and 2.23.2 (Java 11 beta).
