# Patch Next advisory brief: CVE-2018-1000632

Advisory: Dom4j contains a XML Injection vulnerability
IDs: CVE-2018-1000632, GHSA-6pcc-3rfx-4gpm
Record: https://patchnext.com/advisories/cve-2018-1000632 (revision 1, source checked 26 Oct 2026, 16:05 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: org.dom4j:dom4j 2.1.1, 2.0.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven dom4j:dom4j: affected <= 1.6.1
- Maven org.dom4j:dom4j: affected < 2.0.3; >= 2.1.0, <= 2.1.0; fixed in 2.0.3, 2.1.1

## Suggested inspection (read-only)
- Maven dom4j:dom4j: check the installed version with your package manager.
- Maven org.dom4j:dom4j: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on dom4j:dom4j, org.dom4j:dom4j.
- 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.

## Sources
- Verified: https://github.com/advisories/GHSA-6pcc-3rfx-4gpm (GitHub-reviewed advisory GHSA-6pcc-3rfx-4gpm lists affected ranges: Maven org.dom4j:dom4j >=0 =2.1.0 =0 <=1.6.1)
