This vulnerability can also be exploited by using APIs in the specified Component, e.g. through a web service which supplies data to the APIs. CVSS 3.0 Base Score 9.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H).

From the Ubuntu Security Team

Krzysztof Szafrański discovered that the Scripting component did not properly restrict access to the scripting engine in some situations. An attacker could use this to specially construct an untrusted Java application or applet that could escape sandbox restrictions.
