Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.17% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs gradle gradle 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: Within 30 daysRemediation target: Within 180 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

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

6 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.

What, why and how

Gradle is a build automation tool, and its native-platform tool provides Java bindings for native APIs. When resolving dependencies in versions before 9.3.0, some exceptions were not treated as fatal errors and would not cause a repository to be disabled. If a build encountered one of these exceptions, Gradle would continue to the next repository in the list and potentially resolve dependencies from a different repository. If a Gradle build used an unresolvable host name, Gradle would continue to work as long as all dependencies could be resolved from another repository. An unresolvable host name could be caused by allowing a repository's domain name registration to lapse or typo-ing the real domain name. This behavior could allow an attacker to register a service under the host name used by the build and serve malicious artifacts. The attack requires the repository to be listed before others in the build configuration. Gradle has introduced a change in behavior in Gradle 9.3.0 to stop searching other repositories when encountering these errors.

Why

The product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere.

How

An attacker operating through a network path may attempt exploitation when the stated preconditions are met. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

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
a network path → Inclusion of Functionality from Untrusted Control Sphere → cause the confidentiality, integrity or availability impact described by the vendor

Network
Privileges required
None: unauthenticated exploitation is possible

CWE-829: Inclusion of Functionality from Untrusted Control Sphere. The product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere.

JVN iPedia · Japanese · JVNDB-2026-004124Gradle Inc.のGradleにおける複数の脆弱性

Gradleはビルド自動化ツールであり、そのnative-platformツールはネイティブAPI向けのJavaバインディングを提供します。バージョン9.3.0未満の依存関係解決時において、一部の例外が致命的なエラーとして扱われず、リポジトリが無効化されない場合がありました。ビルドがこれらの例外のいずれかに遭遇すると、Gradleはリスト内の次のリポジトリへ処理を続け、別のリポジトリから依存関係を解決する可能性がありました。解決不能なホスト名を使用したGradleビルドでは、すべての依存関係が他のリポジトリで解決可能であれば、Gradleは引き続き動作しました。解決不能なホスト名は、リポジトリのドメイン名登録が失効したり、実際のドメイン名を誤って入力した場合に発生します。この挙動により、攻撃者がビルドで使用されるホスト名の下にサービスを登録し、悪意のあるアーティファクトを提供できる可能性があります。この攻撃は、リポジトリがビルド設定で他よりも先にリストされていることが要件となります。Gradleはバージョン9.3.0で振る舞いを変更し、これらのエラーに遭遇した際には他のリポジトリの検索を中止するようにしました。

Patch and workaround

Operational remediation based on structured source evidence.

Status
?Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change.
Fix availability varies by product
Affected
gradle: < 9.3.0
Fixed
An authoritative update reference is available, but the fixed version is not recorded in the structured CVE fields. Check the linked vendor advisory for the applicable release.
Action
Use the product-specific evidence above. Patch only products with a verified fixed release, and keep every affected or under-investigation state without a matching fix in the remediation queue.
Workaround
No verified workaround is recorded. If business-safe, reduce exposure to the affected interface and allow only trusted sources until authoritative guidance is available.
