Affected versions of MISP inconsistently enforced email-address visibility in DashboardsController::listTemplates().
The query always fetched User.email, while redaction happened only inside the non-REST rendering branch. As a result, the same authenticated user who saw redacted data in the normal HTML interface could request the REST/JSON representation and receive template owners’ email addresses without the intended privilege check.
The fix moves the decision to a centralized User::canSeeEmails() authorization helper. Email addresses are now fetched only when the requester is a site administrator or the instance explicitly enables Security.disclose user emails. The same helper is also reused by other dashboard widgets to keep email-disclosure policy consistent.
Version affected: ≤2.5.45
