An XXE issue in SAXBuilder in JDOM through 2.0.6 allows attackers to cause a denial of service via a crafted HTTP request.
A carefully crafted or corrupt zip file can cause an OOM in Apache Tika's RecursiveParserWrapper in versions 1.7-1.21. Users should upgrade to 1.22 or later.
A carefully crafted package/compressed file that, when unzipped/uncompressed yields the same file (a quine), causes a StackOverflowError in Apache Tika's RecursiveParserWrapper in versions 1.7-1.21. Apache Tika users should upgrade to 1.22 or later.
Apache Tika 1.19 included an incomplete fix for CVE-2018-11761 which added an entity expansion limit for XML parsing. However, Tika reuses SAXParsers and calls reset() after each parse, which, for Xerces2 parsers, as per the documentation, removes the user-specified SecurityManager and thus removes entity expansion limits after the first parse. Apache Tika 1.19 is therefore still vulnerable to entity expansions which can lead to a denial of service attack.

In Apache Tika 0.1 to 1.18, the XML parsers were not configured to limit entity expansion. They were therefore vulnerable to an entity expansion vulnerability which can lead to a denial of service attack.
Apache Tika before version 1.18 has a command injection vulnerability in tika-server. A remote attacker could exploit this to execute arbitrary commands via crafted headers.

Apache Tika before 1.13 does not properly initialize the XML parser or choose handlers, which might allow remote attackers to conduct XML External Entity (XXE) attacks via vectors involving (1) spreadsheets in OOXML files and (2) XMP metadata in PDF and other file formats, a related issue to CVE-2016-2175.
