DescriptionCVE.org

Vulnerability in Oracle Java SE (component: JavaFX). The supported version that is affected is Oracle Java SE: 8u491. 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 the JavaFX component of Oracle Java SE 8u491 is remotely exploitable by unauthenticated attackers across multiple network protocols, confirmed by Oracle's Critical Patch Update for July 2026. The vulnerability manifests in two distinct deployment contexts: server-side web services that pass externally supplied data to JavaFX APIs, and client-side sandboxed environments (Java Web Start applications or Java applets) that load and execute untrusted internet code. No public exploit has been identified at time of analysis, and active exploitation has not been confirmed by CISA KEV; however, the low-complexity, no-authentication-required attack surface makes exploitation straightforward should a proof-of-concept emerge.

Technical ContextAI

JavaFX is a rich-client UI framework bundled with Oracle Java SE 8, providing rendering, media, and web capabilities. The affected product is Oracle Java SE 8u491 (CPE: cpe:2.3:a:oracle_corporation:oracle_java_se:*:*:*:*:*:*:*:*), with the vulnerability scoped specifically to the JavaFX component. Oracle has not disclosed a CWE root cause class (listed as N/A), so the precise defect - whether resource exhaustion, improper input validation, or a parsing fault - is not publicly confirmed. The multi-protocol attack surface implies the flaw may reside in a network-accessible API layer that handles attacker-supplied data, rather than a single protocol-specific handler. The sandbox note is significant: Java SE 8 applet/Web Start deployments inherently load and execute untrusted third-party code, expanding the attack surface to any end-user browser or desktop running this legacy configuration.

RemediationAI

Apply the patch provided in Oracle's Critical Patch Update for July 2026, available at https://www.oracle.com/security-alerts/cpujul2026.html. The advisory will specify the exact patched update release superseding 8u491; the patched version number is not independently confirmed in the available intelligence - consult the advisory directly for the precise target version. If immediate patching is not possible, consider the following compensating controls with noted trade-offs: restrict network access to services that expose JavaFX APIs via firewall or application-layer controls (trade-off: may disrupt legitimate service consumers); disable Java Web Start and browser applet support entirely if those client-side deployment modes are not operationally required (trade-off: breaks legacy Java applet workflows); and isolate Java SE 8 workloads behind authenticated network segments to reduce unauthenticated access exposure (trade-off: adds network segmentation overhead).
