CVE-2026-0637Hinoki check available

Sensitive-data disclosure via irrelevant-property warn logging

Published Aug 6, 2026 · Updated Aug 6, 2026

Information disclosure in WSO2 Event Publisher components allows local users to read sensitive adapter properties from wso2carbon logs. EventPublisherConfigurationBuilder concatenates each irrelevant output-adapter propertyValue into a warning instead of omitting the value. Exploitation requires a misconfigured output adapter and high-privilege access to the local log files; the documented consequence is disclosure only.
