How to fix

Fixed in: 7.15.2, 8.10.2

Technical details

The V8 JSON:API update path (updateRecord and processAttributes functions) fails to strip the id attribute before assigning user-supplied data to SugarBean objects, allowing authenticated attackers to substitute a victim record identifier and bypass owner-only ACL checks (ACL_ALLOW_OWNER). This enables record overwrites and ownership transfer without proper authorization, exploitable over the network by any authenticated user.
