Vulnerability details
The vulnerability allows a remote user to bypass access controls, overwrite CRM records, and hijack record ownership.
The vulnerability exists due to missing filtering of the user-controlled id attribute in the V8 JSON:API processAttributes() function when processing user-supplied attributes for the updateRecord() endpoint before passing them to SugarBean.
