DescriptionCVE.org

Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Security). 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, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data as well as unauthorized read access to a subset of 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 6.5 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N).

AnalysisAI

Oracle Java SE's Security component across versions 8u491 through 26.0.1 - and GraalVM for JDK/Enterprise Edition counterparts - contains an authentication bypass that allows unauthenticated network attackers to perform unauthorized read and write operations against data accessible by the Java runtime. Oracle classifies this as 'easily exploitable' via multiple protocols with no user interaction required, reachable either through server-side web services consuming Security APIs or through sandboxed Java Web Start and applet clients loading untrusted code. No public exploit code or CISA KEV listing has been identified at time of analysis, but the no-complexity network vector across a ubiquitous technology warrants priority patching.

Technical ContextAI

The vulnerability is rooted in the Security component of Oracle Java SE - the suite of packages governing cryptographic operations, authentication policy enforcement, and trust management (java.security, javax.security, and related subsystems including JSSE, JCE, and JAAS). The 'Authentication Bypass' tag in the intelligence metadata indicates the flaw permits circumvention of security policy or trust verification within these APIs rather than a simple crash or data corruption. The CWE is listed as N/A, so no formal root-cause class has been assigned by NVD. Oracle's description confirms the attack surface spans 'multiple protocols,' consistent with Security API usage across HTTPS, LDAP, Kerberos, and other network-facing Java services. The secondary attack surface - sandboxed Java Web Start applications and applets loading untrusted code - reflects the historic browser-plugin Java sandbox model, still technically present in older JRE deployments. CPE identifiers confirm three distinct product lines are affected: cpe:2.3:a:oracle_corporation:oracle_java_se, cpe:2.3:a:oracle_corporation:oracle_graalvm_for_jdk, and cpe:2.3:a:oracle_corporation:oracle_graalvm_enterprise_edition.

RemediationAI

Apply Oracle's Critical Patch Update for July 2026, detailed at https://www.oracle.com/security-alerts/cpujul2026.html. The advisory covers all three affected product lines; administrators should consult the CPU patch availability matrix to identify the exact remediated build for their installed Java SE or GraalVM version, as specific fixed build numbers were not extracted from the available intelligence data - confirmed fix versions should be verified directly against Oracle's CPU documentation before deployment. As a compensating control for server-side deployments that cannot be patched immediately, restrict network access to Java-based web services exposing Security APIs to trusted internal network segments, reducing exposure from internet-facing networks where unauthenticated access is most dangerous - note this does not eliminate risk from internal threats. For client-side environments running Java Web Start or browser applets loading untrusted code, disabling or removing the Java browser plugin and Web Start runtime eliminates that secondary attack surface entirely, with the trade-off of breaking legacy Java applet workflows that depend on these mechanisms. Environments running multiple Java versions (LTS and current) should prioritize patching all active runtime versions simultaneously, as this CVE spans the entire supported Java version range.
