Summary
Vulnerability in Oracle Java SE (component: Compiler) affects version 26.0.2. A difficult-to-exploit attack by an unauthenticated attacker with network access via multiple protocols can cause a hang or frequently repeatable crash (complete DoS). The vulnerability can only be exploited by supplying data to APIs in the specified component without using untrusted Java Web Start applications or untrusted Java applets, such as through a web service. CVSS 3.1 Base Score 5.9 (availability impact).
Risk Assessment
An attacker can remotely cause Java application unavailability, potentially disrupting dependent services. The risk mainly affects systems exposing the compiler API over the network.
Recommendation
Update Oracle Java SE to a version containing the fix and restrict network access to services using the Compiler component.
