"The version of Atlassian Confluence Server running on the remote host is affected by a vulnerability as referenced in
the CONFSERVER-101788 advisory.

  - 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. (CVE-2025-66516)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
