Answer in brief
CVE-2026-1728 records a Critical severity (CVSS 9.8) vulnerability in Privilege Escalation via System REST APIs in Multiple WSO2 Products Permits Admin Account Takeover. The current sources do not mark it as known exploited. The current feed maps WSO2/WSO2 API Control Plane (generic), WSO2/WSO2 API Manager (generic), WSO2/WSO2 Carbon API Manager Rest API Common Functions (generic), WSO2/WSO2 Carbon API Manager Rest API Utility (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.

Tokens issued to a low-privileged user are not sufficiently restricted, allowing them to be used to access product-level Admin REST APIs. Exploitation of this vulnerability allows a low-privileged user to invoke the Admin REST APIs of WSO2 products, potentially leading to full administrative account takeover. This requires the attacker to already possess a low-privileged user account and be able to obtain a valid token for it.
