CVE-2026-40998
Jaxp13 XPath XXE via StreamSource and SAXSource
Description

Jaxp13XPathTemplate evaluated XPath expressions for StreamSource and SAXSource inputs using a code path that parsed attacker-controlled XML with the JDK's default DocumentBuilderFactory behavior instead of Spring's hardened parser configuration. Applications that evaluate XPath against untrusted XML payloads could therefore be exposed to XML External Entity (XXE) style attacks. Affected versions: Spring Web Services 5.0.0 through 5.0.1; 4.1.0 through 4.1.3; 4.0.0 through 4.0.18; 3.1.0 through 3.1.8.

The Common Vulnerability Scoring System is a standardized framework for assessing the severity of vulnerabilities in software and systems. We collect and displays CVSS scores from various sources for each CVE.
Score Version Severity Vector Exploitability Score Impact Score Source
CVSS 3.1 HIGH dcf2e128-44bd-42ed-91e8-88f912c1401d
CVSS 3.1 HIGH [email protected]
Solution
Update Spring Web Services to a patched version to address XXE vulnerabilities.
  • Update Spring Web Services to a fixed version.
  • Configure DocumentBuilderFactory with hardened settings.
  • Avoid parsing untrusted XML with default parsers.
