CVE-2026-40998: Broadcom Spring Web Services

High severity, CVSS 8.2. EPSS: 0.4% chance of exploitation in the next 30 days.

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

• Broadcom Spring Web Services: before 3.1.9 (fixed in 3.1.9); from 4.0.0, before 4.0.19 (fixed in 4.0.19); from 4.1.0, before 4.1.3.1 (fixed in 4.1.3.1); from 5.0.0, before 5.0.1.1 (fixed in 5.0.1.1)
