Loop with Unreachable Exit Condition (Infinite Loop)
A carefully crafted (or fuzzed) file can trigger an infinite loop in Apache Tika `BPGParser`.

Improper Restriction of XML External Entity Reference
Tika reuses SAXParsers and calls `reset()` after each parse; the parser ignores entity expansion limits after the first parse.

Apache Tika has XXE vulnerability
Critical XXE in Apache Tika tika-core (1.13-3.2.1), tika-pdf-module (2.0.0-3.2.1) and tika-parsers (1.13-1.28.5) modules on all platforms allows an attacker to carry out XML External Entity injection via a crafted XFA file inside of a PDF.

This CVE covers the same vulnerability as in CVE-2025-54988. However, this CVE expands the scope of affected packages in two ways.

First, while the entrypoint for the vulnerability was the tika-parser-pdf-module as reported in CVE-2025-54988, the vulnerability and its fix were in tika-core. Users who upgraded the tika-parser-pdf-module but did not upgrade tika-core to >= 3.2.2 would still be vulnerable.

Second, the original report failed to mention that in the 1.x Tika releases, the PDFParser was in the "org.apache.tika:tika-parsers" module.

Loop with Unreachable Exit Condition (Infinite Loop)
A carefully crafted (or fuzzed) file can trigger an infinite loop in Apache Tika `ChmParser`.

Improper Restriction of XML External Entity Reference
Apache Tika 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.
