CVE-2025-66516
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.
