description
OpenProject may render rich-text references in work-package notification emails using the comment author's permissions instead of the recipient's permissions. An authenticated user who can access a private work package can cause a mentioned user without access to receive its subject, type, or status in an email.
mitigation
Upgrade OpenProject / opf/openproject to No patched version known at time of report. or later.
