Doc Text:
A flaw was found in Spring Web Services. This vulnerability allows a remote attacker to perform XML External Entity (XXE) attacks by evaluating XPath expressions against untrusted XML payloads. This occurs because the system uses the JDK's default DocumentBuilderFactory behavior instead of a hardened parser configuration, potentially leading to information disclosure or other system impacts.

Description OSIDB Bzimport 2026-06-11 07:01:17 UTC 
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.
