Severity: low Affected versions:
- Apache CXF (org.apache.cxf:cxf-rt-rs-security-sso-oidc) 4.2.0 before 4.2.4 - Apache CXF (org.apache.cxf:cxf-rt-rs-security-sso-oidc) 4.0.0 before 4.1.9 - Apache CXF (org.apache.cxf:cxf-rt-rs-security-sso-oidc) before 3.6.13 Description: The max_age authentication-freshness check in OidcClientCodeRequestFilter was inoperative due to a milliseconds/seconds unit mismatch and an inverted comparison polarity. Any relying party using setMaxAgeOffset to enforce re-authentication would silently accept sessions of any age, bypassing step-up authentication policies. Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.
