Technical details

The vulnerability is a missing authorization check (CWE-862) in the inplace-edit dialog handler. When a non-admin authenticated user requests the edit dialog for a custom field using its raw identifier, the endpoint bypasses the normal admin_only visibility scope validation and renders stored field comments in read-only mode. The attack requires authentication and project membership but no special privileges. An attacker can disclose custom-field comment text only; the vulnerability does not permit disclosure of field values or mutation of data. The issue is patched in versions 17.5.2 and 17.6.0.
