Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Liferay Portal from 7.4.0 through 7.4.3.111 (the release.portal.bom Maven package, affected from 7.4.0-ga1 to before 7.4.3.112-ga112) has a flaw in its Profile Widget, which puts a user's name into the Content-Disposition header when a vCard file is downloaded. A remote authenticated user can exploit this to change the downloaded file's extension. Upgrade to 7.4.3.112-ga112 or later to fix the issue.
