CVE-2026-40997

SOAP security faults leak Spring Security account state

Published: Jun 11, 2026Updated: Jun 11, 2026 Sources: CVE List NVD
NVD MITRE
5.3CVSS
MEDIUM

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.
