CVE-2025-30749 is a high-severity vulnerability in Oracle GraalVM for JDK and Oracle Java SE, specifically affecting the 2D component. The CVSS score of 8.1 indicates a significant risk, particularly as it allows unauthenticated attackers with network access to exploit the vulnerability across multiple protocols. This can lead to the potential takeover of affected systems.
The urgency for organizations to address this vulnerability is critical due to its exploitability. The vulnerability primarily impacts Java deployments that run sandboxed Java Web Start applications or applets that may execute untrusted code. The vulnerability does not affect server deployments that only load trusted code.
Organizations utilizing affected versions of Oracle GraalVM and Java SE must act swiftly. The potential risks include unauthorized access and control over systems, making it essential to patch the affected components promptly.
Given the nature of the vulnerability and the potential impact on confidentiality, integrity, and availability, organizations should prioritize remediation to mitigate risks associated with CVE-2025-30749.
Vulnerability Details
The vulnerability allows an unauthenticated attacker with network access to compromise the Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition. The affected versions include Oracle Java SE: 8u451, 8u451-perf, 11.0.27, 17.0.15, 21.0.7, and 24.0.1; Oracle GraalVM for JDK: 17.0.15, 21.0.7, and 24.0.1; and Oracle GraalVM Enterprise Edition: 21.3.14.
The vulnerability is classified under CVSS 3.1 with a base score of 8.1, indicating high severity. The CVSS vector reflects high impacts on confidentiality, integrity, and availability.
Technical Analysis
The root cause of this vulnerability lies in the handling of untrusted code executed in sandboxed environments. The attack vector is network-based, with high complexity due to the requirements for specific conditions to exploit successfully.
No privileges are required for successful exploitation, and no user interaction is necessary. This vulnerability poses high risks, as an attacker can potentially gain full control over the affected systems.
Risk & Impact Analysis
Organizations running vulnerable versions of Oracle Java SE and GraalVM are at significant risk, especially in environments where untrusted code is executed. The blast radius extends to all systems leveraging these technologies in insecure configurations.
Given the CVSS score of 8.1, organizations should address this vulnerability in their priority patch cycle to prevent potential system takeovers and data breaches.
