CVE-2021-33330

Liferay Portal 7.2.0 through 7.3.2, and Liferay DXP 7.2 before fix pack 9, allows access to Cross-origin resource sharin

Liferay Portal 7.2.0 through 7.3.2, and Liferay DXP 7.2 before fix pack 9, allows access to Cross-origin resource sharing (CORS) protected resources if the user is only authenticated using the portal session authentication, which allows remote attackers to obtain sensitive information including the targeted user’s email address and current CSRF token.
