Description
A flaw was found in OpenJDK's Abstract Window Toolkit (AWT). A remote attacker with low privileges could exploit this vulnerability by convincing a user to run untrusted code within a sandboxed environment. Successful exploitation allows unauthorized read access to a subset of accessible data, leading to information disclosure.
Statement
This vulnerability is evaluated as having a Low severity impact because exploitation requires complex prerequisites, including user interaction and authenticated access to an untrusted execution environment. Standard deployments across Red Hat Enterprise Linux and enterprise runtimes run only trusted server-side workloads rather than sandboxed client applications. Consequently, default production systems do not expose this attack vector, restricting the risk of unauthorized data disclosure to non-standard client configurations.
