EPSS

• CVE-2023-4218: 0.39% estimated exploitation activity in the next 30 days; percentile 33.14 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact xml files like ".project" are parsed vulnerable against all sorts of XXE attacks. The user just needs to open any evil project or update an open project with a vulnerable file (for example for review a foreign repository or patch). Vulnerablility was found by static code analysis (SonarLint). Example .project file: Patches Similar patches including junit test that shows the vulnerability have already applied to PDE (see https://github.com/eclipse-pde/eclipse.pde/pull/667). A solution to platform should be the same: just reject parsing any XML that contains any DOCTYPE. Workarounds No known workaround. User can only avoid to get/open any foreign files with eclipse. Firewall rules against loss of data (but not against XML bomb).

# Patch Next advisory brief: CVE-2023-4218

Advisory: Eclipse IDE XXE in eclipse.platform
IDs: CVE-2023-4218, GHSA-j24h-xcpc-9jw8
Record: https://patchnext.com/advisories/cve-2023-4218 (revision 1, source checked 26 Oct 2026, 16:29 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.0)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.eclipse.jdt:org.eclipse.jdt.ui 3.30.0; org.eclipse.platform:org.eclipse.core.runtime 3.29.0; org.eclipse.platform:org.eclipse.ui.workbench 3.130.0; org.eclipse.platform:org.eclipse.jface 3.31.0; org.eclipse.platform:org.eclipse.platform 4.29.0; org.eclipse.platform:org.eclipse.urischeme 1.3.100; org.eclipse.platform:org.eclipse.ui.forms 3.13.0; org.eclipse.platform:org.eclipse.ui.ide 3.21.100. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.eclipse.jdt:org.eclipse.jdt.ui: affected < 3.30.0; fixed in 3.30.0
- Maven org.eclipse.platform:org.eclipse.core.runtime: affected < 3.29.0; fixed in 3.29.0
- Maven org.eclipse.platform:org.eclipse.ui.workbench: affected < 3.130.0; fixed in 3.130.0
- Maven org.eclipse.platform:org.eclipse.jface: affected < 3.31.0; fixed in 3.31.0
- Maven org.eclipse.platform:org.eclipse.platform: affected < 4.29.0; fixed in 4.29.0
- Maven org.eclipse.platform:org.eclipse.urischeme: affected < 1.3.100; fixed in 1.3.100
- Maven org.eclipse.platform:org.eclipse.ui.forms: affected < 3.13.0; fixed in 3.13.0
- Maven org.eclipse.platform:org.eclipse.ui.ide: affected < 3.21.100; fixed in 3.21.100

## Suggested inspection (read-only)
- Maven org.eclipse.jdt:org.eclipse.jdt.ui: check the installed version with your package manager.
- Maven org.eclipse.platform:org.eclipse.core.runtime: check the installed version with your package manager.
- Maven org.eclipse.platform:org.eclipse.ui.workbench: check the installed version with your package manager.
- Maven org.eclipse.platform:org.eclipse.jface: check the installed version with your package manager.
- Maven org.eclipse.platform:org.eclipse.platform: check the installed version with your package manager.
- Maven org.eclipse.platform:org.eclipse.urischeme: check the installed version with your package manager.
- Maven org.eclipse.platform:org.eclipse.ui.forms: check the installed version with your package manager.
- Maven org.eclipse.platform:org.eclipse.ui.ide: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.eclipse.jdt:org.eclipse.jdt.ui, org.eclipse.platform:org.eclipse.core.runtime, org.eclipse.platform:org.eclipse.ui.workbench, org.eclipse.platform:org.eclipse.jface, org.eclipse.platform:org.eclipse.platform, org.eclipse.platform:org.eclipse.urischeme, org.eclipse.platform:org.eclipse.ui.forms, org.eclipse.platform:org.eclipse.ui.ide.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
