Description
Affected versions of cti-transmute fail to apply comment-level access-control rules when generating evaluation report exports. Although normal comment retrieval filters comments according to conversion visibility, comment privacy, ownership, authorship, and administrative privileges, build_evaluation_report() previously included all evaluation comments without applying those rules. Consequently, a user who was authorized to view a conversion could export its evaluation report as Markdown or PDF and obtain private evaluation comments that should only have been visible to the conversion owner, the comment author, or an administrator. The leaked report data also contained the comment author's name. The fix passes the requesting user into the report builder and filters every evaluation comment using the shared access.can_see_comment() authorization function.
