| Title | Omega Solution CoinEx Crypto latest Authorization Bypass |
|---|
| Description | Omega Solution CoinEx Crypto 2025 contains an Insecure Direct Object Reference (IDOR) vulnerability in the customer profile update functionality. The application fails to enforce object-level authorization when processing profile update requests and directly trusts a user-controlled customer identifier to determine the target resource. An authenticated customer can manipulate the customer identifier in the request path to update profile information belonging to another customer without authorization. Successful exploitation results in unauthorized modification of customer account data, including profile information such as name, email address, telephone number, and other editable fields, leading to horizontal privilege escalation and compromise of data integrity.
