Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.58% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs assertj assertj and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Cross-source reconciliation

Remediation availability differs by product scope

Verified remediation exists for at least one product or source, but 4 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Distribution package intelligence

Release-specific package status

Debian, ubuntu findings are scoped to the named distribution, release and source package. An absent finding does not mean a package is unaffected.

5 package states
Package result overrides the generic status

BlackTree has verified remediation for at least one product or source, but the relevant distribution still reports no fixed package for 4 affected package states shown here. Treat those rows as affected with no fix until that distribution publishes a fixed version.

Repository candidate not checked

A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

Summary
A flaw was found in AssertJ. An XML External Entity (XXE) vulnerability exists in the `XmlStringPrettyFormatter` component, which is used by the `isXmlEqualTo(CharSequence)` assertion. If an application processes untrusted XML input using these methods, a remote attacker could exploit this flaw to read arbitrary local files, perform Server-Side Request Forgery (SSRF) by making the server request arbitrary URLs, or cause a Denial of Service (DoS) through entity expansion attacks.

01

What, why and how

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.

Why

The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may obtain information outside the intended access boundary.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
local access → Improper Restriction of XML External Entity Reference → obtain information outside the intended access boundary

JVN iPedia · Japanese · JVNDB-2026-006706AssertJにおけるXML 外部エンティティの脆弱性

AssertJはJavaおよびJava仮想マシン(JVM)向けのFluentテストアサーションを提供するツールです。バージョン1.4.0から3.27.7未満の間、`org.assertj.core.util.xml.XmlStringPrettyFormatter`にXML外部エンティティ(XXE)脆弱性が存在していました。具体的には、`toXmlDocument(String)`メソッドが`DocumentBuilderFactory`をデフォルト設定で初期化しており、DTDや外部エンティティを無効化していなかったためです。このフォーマッターは、`CharSequence`値に対する`isXmlEqualTo(CharSequence)`アサーションで使用されています。アプリケーションが信頼されていないXML入力を`org.assertj.core.api.AbstractCharSequenceAssert`の`isXmlEqualTo(CharSequence)`または`org.assertj.core.util.xml.XmlStringPrettyFormatter`の`xmlPrettyFormat(String)`で処理すると脆弱性が生じます。これらのメソッドで信頼されていないXML入力を処理する場合、攻撃者は`file://`URI(例:`/etc/passwd`やアプリケーション設定ファイル)を介して任意のローカルファイルを読み取ったり、HTTP/HTTPS URIを利用したサーバーサイドリクエストフォージェリ(SSRF)を行ったり、「ビリオンラフ」エンティティ展開攻撃によるサービス拒否(DoS)を引き起こす可能性があります。`isXmlEqualTo(CharSequence)`はバージョン3.18.0でXMLUnitに置き換えられ非推奨となり、バージョン4.0で削除される予定です。影響を受けるバージョンのユーザーには、優先的に`isXmlEqualTo(CharSequence)`をXMLUnitに置き換えること、バージョン3.27.7にアップグレードすること、または信頼されていない入力に対して`isXmlEqualTo(CharSequence)`や`XmlStringPrettyFormatter`を使用しないことを推奨します。`XmlStringPrettyFormatter`はこれまで`isXmlEqualTo(CharSequence)`のユーティリティとして扱われており、バージョン3.27.7で非推奨となり、4.0で削除されますが代替手段はありません。
