Fixed In Version: tika 1.13
Doc Type: Bug Fix
Doc Text:
It was found that the parsing of OOXML, XMP in PDF, and some other file formats by Apache Tika would expand entity references. A remote, unauthenticated attacker could use this flaw to read files accessible to the user running the application server, and potentially perform other more advanced XXE attacks.

Description Andrej Nemec 2016-05-27 09:10:57 UTC 
Apache Tika parses XML within numerous file formats.  In some instances, such as spreadsheets in OOXML files, XMP in PDF, and other file formats, the initialization of the XML parser or the choice of handlers did not protect against XML External Entity (XXE) vulnerabilities.
