Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Liferay Portal 7.2.0 through 7.4.1 and Liferay DXP 7.2 before fix pack 15 and 7.3 before update 4 are vulnerable to user impersonation. A remote authenticated user who accesses linked content created through the WYSIWYG editor while another user is being impersonated can leak the impersonation parameter and impersonate that user. Upgrade Liferay Portal to 7.4.2 or later, or Liferay DXP to 7.2.10.fp15 or 7.3.10.u4 or later. The source gives few details about the exact conditions.
