was-portal-cve20136316-info-disc (88597) The risk level is classified as MediumMedium Risk


A vulnerability in IBM WebSphere Portal could allow a remote attacker to obtain sensitive information. In some specific situations, when using Web Content Manager (WCM) context processors in combination with rendering Taxonomy components, the access control restrictions on individual categories in the taxonomy are not always enforced correctly. This occurs if the context processor changes the effective content selection. Properties of WCM content could be displayed to users, who do not have access rights to see them.
