There is no fixed version for RHEL:7 cxf-rt-ws-security.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cxf-rt-ws-security package and not the cxf-rt-ws-security package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

In Apache CXF, STSTokenValidator checks whether a SAML assertion is signed by a trusted certificate before deciding to send it to the STS. That result was stored in one object shared by all requests, so one request could read another's result. A remote, unauthenticated attacker could send a forged assertion signed with an untrusted certificate while legitimate requests were being processed, and it could be accepted as trusted without ever reaching the STS. Only services that use STSTokenValidator to validate SAML tokens without alwaysValidateToSts set are affected.  Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.
