Summary

Ekushey Project Manager CRM through version 5.0 contains a missing uniqueness constraint vulnerability that allows authenticated administrators to create duplicate client accounts with identical email and password credentials. Attackers can exploit the lack of email field uniqueness enforcement to create conflicting account states where multiple accounts share the same email address with different passwords, resulting in unpredictable authentication behavior and unauthorized account access.
