- Severity: high (CVSS 8.2 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.4% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-06-11 · updated 2026-09-04
- Weakness: CWE-611
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.
Affected products
- Spring Web Services: before 3.1.9; from 4.0.0 before 4.0.19; from 4.1.0 before 4.1.3.1; from 5.0.0 before 5.0.1.1 — fixed in 3.1.9, 4.0.19, 4.1.3.1, 5.0.1.1
How to fix
Upgrade to a fixed version: Spring Web Services 3.1.9, 4.0.19, 4.1.3.1, 5.0.1.1. Check the vendor advisory for mitigations.
