Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: JAXP). Supported versions that are affected are Oracle Java SE: 8u461, 8u461-perf, 11.0.28, 17.0.16, 21.0.8, 25; Oracle GraalVM for JDK: 17.0.16 and 21.0.8; Oracle GraalVM Enterprise Edition: 21.3.15. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. CVSS 3.1 Base Score 7.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
Security readout for executives and security teams
Plain-English summary
CVE-2025-53066 is a high-severity information disclosure issue in Oracle Java and GraalVM JAXP. A remote, unauthenticated attacker may access critical data when affected Java components process supplied data through relevant APIs.
Executive priority
Prioritize remediation in the next high-priority patch cycle, especially for internet-facing Java services. The business risk is unauthorized access to sensitive data, not system takeover based on the provided CVSS impacts.
Technical view
The issue is classified as CWE-200 in JAXP. Oracle rates it CVSS 7.5 with network attack vector, low complexity, no privileges, no user interaction, and high confidentiality impact. Integrity and availability impacts are not listed.
Likely exposure
Exposure is most likely where affected Java SE or GraalVM versions process untrusted data through JAXP, including web services feeding data into those APIs. Sandboxed Java Web Start or applet deployments relying on the Java sandbox are also in scope.
Exploitation context
The source bundle says the vulnerability is easily exploitable over multiple protocols. It also says KEV is false, and no provided source states active exploitation. Treat exploit status as unconfirmed, not known exploited.
Researcher notes
The bundle does not provide root cause details, proof-of-concept status, exploit artifacts, or exact fixed build numbers. Avoid assuming affected downstream products beyond Oracle, Debian LTS context, and Siemens advisory coverage without vendor confirmation.
Mitigation direction
Inventory Oracle Java SE and GraalVM versions against the affected version list.
Follow Oracle CPU October 2025 guidance for applicable updates or mitigations.
Check Debian LTS and Siemens advisories where those distributions or products are used.
Prioritize internet-facing services that pass untrusted data into JAXP APIs.
Reduce untrusted Java sandbox exposure where still present.
Validation and detection
Confirm runtime versions: Java SE, GraalVM for JDK, and GraalVM Enterprise Edition.
Identify services, APIs, or products that use JAXP with untrusted input.
Map bundled Java runtimes inside applications, appliances, and vendor products.
Verify Oracle, Debian, or Siemens remediation status for each affected asset.
Confirm monitoring covers unusual data access from exposed Java services.

CWE-200: Information exposure and cloud metadata lookup
Information exposure and SSRF weaknesses can make discovery, cloud metadata, and credential material review relevant. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Exposure of Sensitive Information to an Unauthorized Actor
Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
