Apache CXF has Authentication Bypass in OAuth2 TokenIntrospectionService
Quick fix
GHSA-542g-m3fx-q86f — 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
An authentication bypass vulnerability exists in the OAuth2 TokenIntrospectionService in Apache CXF. Due to a missing 'throw' keyword in the security context check, the introspection endpoint (/services/oauth2/introspect) can be accessed by any unauthenticated network attacker. However note that this is a safeguard only in the case that someone forgot to enable authentication on the service. Users are recommended to upgrade to version 4.2.2 or 4.1.7, which fixes this issue.
