Description
A vulnerability in the Scripting component of Oracle Java SE (OpenJDK 8 and 11) allows an unauthenticated remote attacker to cause a denial of service by triggering a hang or repeated crash. This issue affects certain versions of OpenJDK 8 and 11 prior to fixed releases. The vulnerability can be exploited via network access through multiple protocols and involves APIs that process untrusted code, such as sandboxed Java Web Start applications or applets. The CVSS 3.1 base score is 7.5, indicating high severity with impact on availability. Fixed versions are available and should be applied to mitigate the risk.
