Source description

As published by the source; long descriptions are shortened.

Wss4jSecurityInterceptor initialized its BSP (WS-I Basic Security Profile) compliance flag so that inbound validation disabled WSS4J BSP enforcement on RequestData. Services that validate WS-Security on the network could therefore accept messages that violate BSP rules, weakening protocol-level checks. 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.

# Patch Next advisory brief: CVE-2026-40994

Advisory: Spring Web Services: Wss4jSecurityInterceptor disables WS-I BSP validation by default
IDs: CVE-2026-40994, GHSA-gg9r-wr4p-w63h
Record: https://patchnext.com/advisories/cve-2026-40994 (revision 1, source checked 26 Oct 2026, 16:55 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: org.springframework.ws:spring-ws-security 5.0.2, 4.1.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.springframework.ws:spring-ws-security: affected >= 5.0.0, <= 5.0.1; >= 4.1.0, <= 4.1.3; >= 4.0.0, <= 4.0.18; >= 3.1.0, <= 3.1.8; fixed in 4.1.4, 5.0.2

## Suggested inspection (read-only)
- Maven org.springframework.ws:spring-ws-security: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.springframework.ws:spring-ws-security.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-gg9r-wr4p-w63h (GitHub-reviewed advisory GHSA-gg9r-wr4p-w63h lists affected ranges: Maven org.springframework.ws:spring-ws-security >=5.0.0 =4.1.0 =4.0.0 =3.1.0 <=3.1.8)

Commands are suggestions: review each one before running it.
