# Patch Next advisory brief: CVE-2017-20151

Advisory: iText RUPS XML External Entity vulnerability
IDs: CVE-2017-20151, GHSA-j69f-fgh5-f7mc
Record: https://patchnext.com/advisories/cve-2017-20151 (revision 1, source checked 26 Oct 2026, 16:14 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.itextpdf:itext-rups: affected <= 7.0.1

## Suggested inspection (read-only)
- Maven com.itextpdf:itext-rups: 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 com.itextpdf:itext-rups.
- 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.
