Root Cause Analysis
The patch removes createCallbackId
and related callback_id
tracking from the JavaScript adapter. This code was likely part of the endpoint URL generation mechanism that made internal endpoints accessible. The removal in the security patch indicates these functions were involved in the information exposure vulnerability. During exploitation, these functions would be invoked when processing crafted URLs targeting adapter endpoints.
