A fix is available — apply it.

A weakness has been identified in apidevtools json-schema-ref-parser up to 15.3.5. This impacts the function Refs.set/Pointer.set in the library lib/pointer.ts. Executing a manipulation can lead to improperly controlled modification of object prototype attributes. The attack can be launched remotely. Upgrading to version 15.3.6 will fix this issue. This patch is called a786bc6afc3674f650496472ee93d5cf74c4bd84. It is suggested to upgrade the affected component.
