Apache CXF OAuth2 TOCTOU Race Condition in Refresh Token Processing
Quick fix
GHSA-83r6-96m8-r52p — org.apache.cxf:cxf-rt-rs-security-oauth2: upgrade to the fixed version with the command below.
# pom.xml: bump <version>4.2.2</version> for org.apache.cxf:cxf-rt-rs-security-oauth2Details
A race condition in AbstractOAuthDataProvider allows concurrent requests using the same Refresh Token to bypass single-use semantics and generate multiple valid Access Tokens, when 'recycleRefreshTokens' is set to false. A leaked refresh token can be replayed concurrently by multiple attackers or threads. Users are recommended to upgrade to versions 4.2.2 or 4.1.7, which fixes this issue.
