Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Fess versions before 14.19.2 create temporary files without explicitly restrictive permissions, in the createTempFile() method of SystemHelper. A local user on a shared system could read sensitive data in those files. Upgrade to Fess 14.19.2 or later. Until then, restrict local access to the host running Fess to trusted users only.
