Authorization bypass via direct OSGi class invocation
Published Sep 12, 2025 · Updated Sep 12, 2025
Incorrect authorization in Liferay Portal and DXP allows attackers to bypass JSON web-service access policies via direct class invocation. Affected OSGi services register implementation classes directly, preventing AOP proxies from applying the authorization advice enforced by Service Access Policies. Exploitation requires low privileges on an adjacent network and active user interaction; reachable service methods can expose or alter limited application data.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
