Summary
The Iptanus File Upload WordPress plugin before 5.1.7 does not implement proper file handling when the duplicatepolicy setting is configured to "maintain both." Due to a Time-of-Check to Time-of-Use (TOCTOU) race condition between the file existence check and the actual file write operation, an authenticated attacker can overwrite files uploaded by other users.
