Critical XXE in Apache Tika (tika-parser-pdf-module) in Apache Tika 1.13 through and including 3.2.1 on all platforms allows an attacker to carry out XML External Entity injection via a crafted XFA file inside of a PDF. An attacker may be able to read sensitive data or trigger malicious requests to internal resources or third-party servers. Note that the tika-parser-pdf-module is used as a dependency in several Tika packages including at least: tika-parsers-standard-modules, tika-parsers-standard-package, tika-app, tika-grpc and tika-server-standard.
Users are recommended to upgrade to version 3.2.2, which fixes this issue.

The initial fixes in CVE-2022-30126 and CVE-2022-30973 for regexes in the StandardsExtractingContentHandler were insufficient, and we found a separate, new regex DoS in a different regex in the StandardsExtractingContentHandler. These are now fixed in 1.28.4 and 2.4.1.

We failed to apply the fix for CVE-2022-30126 to the 1.x branch in the 1.28.2 release. In Apache Tika, a regular expression in the StandardsText class, used by the StandardsExtractingContentHandler could lead to a denial of service caused by backtracking on a specially crafted file. This only affects users who are running the StandardsExtractingContentHandler, which is a non-standard handler. This is fixed in 1.28.3.
