Indirect profile-data disclosure via hidden-field search oracle
Published May 7, 2026 · Updated May 7, 2026
Information exposure in Admidio before 5.0.9 allows remote authenticated users to infer hidden profile data through member search results. The members_assignment_data.php endpoint adds hidden birthday and address fields to its SQL search condition before isVisible() filters JSON columns. Exploitation requires a role leader with assign-only rights, a hidden profile field, a known role UUID, and guessed values; the consequence is indirect disclosure of matching members' PII.
