Spring Web Services: SOAP security faults leak Spring Security account state

Moderate severity GitHub Reviewed Published Jun 11, 2026 to the GitHub Advisory Database • Updated Aug 21, 2026

Package

maven org.springframework.ws:spring-ws-security (Maven)

Affected versions

>= 5.0.0, <= 5.0.1
>= 4.1.0, <= 4.1.3
>= 4.0.0, <= 4.0.18
>= 3.1.0, <= 3.1.8

Patched versions

5.0.2
4.1.4

Description

Several Spring WS integration paths with Spring Security could surface detailed account state (for example locked or disabled user semantics) to remote SOAP clients through exception messages or callback outcomes, instead of failing with generic authentication errors. That behavior assists remote attackers in distinguishing valid accounts from invalid ones and inferring lifecycle state.

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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
