DescriptionCVE.org

Vulnerability in Oracle Java SE (component: Libraries). Supported versions that are affected are Oracle Java SE: 8u491, 8u491-perf, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1; Oracle GraalVM for JDK: 17.0.19 and 21.0.11; Oracle GraalVM Enterprise Edition: 21.3.18. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Java SE. 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 5.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).

AnalysisAI

Partial denial-of-service in Oracle Java SE's Libraries component allows unauthenticated network attackers to disrupt availability across a broad range of supported versions, including the current releases 25.0.3 and 26.0.1. The attack surface is unusually wide: exploitation is possible through any protocol supported by the JVM, via APIs exposed in the Libraries component, through web services that internally invoke those APIs, and through the sandboxed Java Web Start or applet execution path when loading untrusted code. No public exploit code has been identified at time of analysis and the vulnerability is not listed in the CISA KEV catalog, though the trivial exploitation conditions (AC:L/PR:N/UI:N) and the ubiquity of Java deployments elevate realistic risk beyond the moderate CVSS score alone.

Technical ContextAI

The affected component is the Libraries subsystem of the Java SE runtime, a foundational layer that underpins core data structures, utility classes, and standard APIs used by virtually all Java applications. The CPE string cpe:2.3:a:oracle_corporation:oracle_java_se:*:*:*:*:*:*:*:* reflects the broad product scope. Affected runtimes span Oracle Java SE versions 8u491 through 26.0.1, Oracle GraalVM for JDK 17.0.19 and 21.0.11 (which share the HotSpot JDK codebase), and Oracle GraalVM Enterprise Edition 21.3.18. The vulnerability affects multiple long-term support (LTS) releases simultaneously (Java 8, 11, 17, 21) as well as the current non-LTS streams (Java 25, 26), indicating a defect in shared library code rather than a version-specific regression. No CWE identifier was assigned by Oracle, so the root-cause class is not disclosed; the partial availability impact and multi-protocol attack surface are consistent with resource exhaustion, improper input handling, or algorithmic complexity weaknesses in library parsing or processing routines.

RemediationAI

Apply the patches released in Oracle's Critical Patch Update for July 2026, available at https://www.oracle.com/security-alerts/cpujul2026.html. Oracle does not publish specific fixed version numbers outside the CPU advisory matrix, so exact replacement versions should be confirmed against the July 2026 CPU release notes. Patch available per vendor advisory - independently confirmed fix versions should be retrieved from the Oracle CPU document before deployment. For environments where immediate patching is not feasible, compensating controls should include network-level restrictions that limit which systems can submit requests to Java service endpoints, particularly those exposing Libraries-component APIs over untrusted networks; restricting inbound protocol diversity (for example, filtering non-HTTP protocols at the perimeter) reduces the multi-protocol attack surface at the cost of legitimate protocol flexibility. For Java 8 deployments still using sandboxed Java Web Start applications, disabling or blocking JNLP execution at the endpoint level eliminates that specific attack path; note that this may break legacy desktop application delivery workflows.
