Pending analysis
Type:
CWE-611 Improper Restriction of XML External Entity Reference ('XXE')
Publication date:
11/06/2026
Last modified:

Description

Jaxp13XPathTemplate evaluated XPath expressions for StreamSource and SAXSource inputs using a code path that parsed attacker-controlled XML with the JDK&amp;#39;s default DocumentBuilderFactory behavior instead of Spring&amp;#39;s hardened parser configuration. Applications that evaluate XPath against untrusted XML payloads could therefore be exposed to XML External Entity (XXE) style attacks.<br /> <br /> Affected versions:<br /> 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.
