Detection Guidance

CVE-2026-3020 is an Identity-Based Authorization Bypass (IDOR) vulnerability in the Wakyma web application that allows an attacker with limited privileges to modify legitimate user account data. Detection involves monitoring for unauthorized changes to user account details such as email address modifications, email validations, and password reset requests initiated by users without proper authorization.

Since this vulnerability requires limited privileges and does not require user interaction, network or system detection can focus on auditing logs for suspicious account modification activities, especially those involving email changes and password reset requests.

Specific commands are not provided in the available resources. However, general approaches include:

• Review application logs for unusual user account modifications.
• Monitor HTTP requests to endpoints handling user data changes for anomalous patterns.
• Use web application firewalls (WAF) to detect and block unauthorized API calls attempting to modify user data.
