"It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1448 advisory.

    AssertJ provides Fluent testing assertions for Java and the Java Virtual Machine (JVM). Starting in
    version 1.4.0 and prior to version 3.27.7, an XML External Entity (XXE) vulnerability exists in
    `org.assertj.core.util.xml.XmlStringPrettyFormatter`: the `toXmlDocument(String)` method initializes
    `DocumentBuilderFactory` with default settings, without disabling DTDs or external entities. This
    formatter is used by the `isXmlEqualTo(CharSequence)` assertion for `CharSequence` values. An application
    is vulnerable only when it uses untrusted XML input with either `isXmlEqualTo(CharSequence)` from
    `org.assertj.core.api.AbstractCharSequenceAssert` or `xmlPrettyFormat(String)` from
    `org.assertj.core.util.xml.XmlStringPrettyFormatter`. If untrusted XML input is processed by tone of these
    methods, an attacker couldnread arbitrary local files via `file://` URIs (e.g., `/etc/passwd`, application
    configuration files); perform Server-Side Request Forgery (SSRF) via HTTP/HTTPS URIs, and/or cause Denial
    of Service via Billion Laughs entity expansion attacks. `isXmlEqualTo(CharSequence)` has been deprecated
    in favor of XMLUnit in version 3.18.0 and will be removed in version 4.0. Users of affected versions
    should, in order of preference: replace `isXmlEqualTo(CharSequence)` with XMLUnit, upgrade to version
    3.27.7, or avoid using `isXmlEqualTo(CharSequence)` or `XmlStringPrettyFormatter` with untrusted input.
    `XmlStringPrettyFormatter` has historically been considered a utility for `isXmlEqualTo(CharSequence)`
    rather than a feature for AssertJ users, so it is deprecated in version 3.27.7 and removed in version 4.0,
    with no replacement. (CVE-2026-24400)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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