Supported versions that are affected are Oracle Java SE: 8u503; Oracle JavaFX: 21.0.12, 25.0.4 and  27; Oracle GraalVM Enterprise Edition: 21.3.19.1.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle JavaFX, Oracle GraalVM Enterprise Edition.  Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in  unauthorized read access to a subset of Oracle Java SE, Oracle JavaFX, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability 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. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.1 Base Score 3.1 (Confidentiality impacts).  CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N).\nA flaw was found in OpenJFX. An unauthenticated remote attacker could exploit this vulnerability by enticing a user to run untrusted code in a sandboxed client environment. Successful exploitation allows the attacker to obtain unauthorized read access to sensitive data, leading to information disclosure.\nThis vulnerability is rated Low severity because successful exploitation requires complex attack conditions alongside user interaction, resulting only in limited, unauthorized data exposure. Red Hat Enterprise Linux and enterprise Java platforms predominantly operate in headless server, container, and build environments where only administrator-approved, trusted code is executed. The flaw primarily poses a threat to client-side configurations executing untrusted mobile code within legacy sandbox architectures, which are not supported or deployed by default in standard Red Hat operating environments.",
