QID 981049

QID 981049: Java (maven) Security Update for org.apache.tika:tika-core (GHSA-h8q5-g2cj-qr5h)

In Apache Tika 1.19 (CVE-2018-11761), we 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 versions from 0.1 to 1.19 are therefore still vulnerable to entity expansions which can lead to a denial of service attack. Users should upgrade to 1.19.1 or later.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.

CVSS V3 rated as High - 7.5 severity.

CVSS V2 rated as Medium - 5 severity.
