Local file disclosure via cacheable download responses

Published Oct 31, 2025 · Updated Oct 31, 2025

Information disclosure in Liferay Portal and Liferay DXP allows local users to read downloaded files from a browser cache. The Document Library WebServerServlet and Adaptive Media AMServlet mark downloaded responses private rather than no-cache, leaving file content in the browser cache. Exploitation requires access to the victim's local browser cache after a file download and exposes only files retained there.
