CVE-2026-0637: WSO2 API Control Plane

Medium severity, CVSS 4.4. EPSS: 0.2% chance of exploitation in the next 30 days.

When an Event Publisher output adapter is configured with irrelevant properties, the affected products log these properties. This logging occurs without sufficient validation or sanitization of the property values. A malicious actor with access to the 'wso2carbon' log files could retrieve sensitive information, such as user credentials or other confidential data, that was inadvertently logged due to misconfiguration, potentially leading to unauthorized access.
