NVD Description

Note: Versions mentioned in the description apply only to the upstream cxf-rt-rs-security-oauth2 package and not the cxf-rt-rs-security-oauth2 package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A race condition in JCacheCodeDataProvider allows an attacker to redeem a single authorization code multiple times via concurrent requests, resulting in the issuance of multiple distinct, valid access tokens. Users are recommended to upgrade to versions 4.2.3, 4.1.8 or 3.6.12, which fix this issue.
