Improper authentication-attempt restriction in Yordam Library Automation System before 20.1 allows remote attackers to enumerate users. The Turkish national CERT record does not identify the affected login endpoint or disclose how authentication responses distinguish valid accounts. The attack requires network reachability but no credentials or user interaction, and the published material does not establish code execution or data modification.
