CVE-2026-71575— Apache CXF: Inoperative max_age authentication-freshness check in OidcClientCodeRequestFilter

Quick assessment

Affected
Apache Software Foundation Apache CXF
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

由于毫秒/秒单位不匹配以及比较极性颠倒，OidcClientCodeRequestFilter 中的 max_age 认证新鲜度检查实际上处于失效状态。任何使用 setMaxAgeOffset 来强制重新身份验证的依赖方（Relying Party）都会静默接受任意年龄的会话，从而绕过逐步提升的认证策略（step-up authentication policies）。建议用户升级到修复了此问题的 4.2.4、4.1.9 或 3.6.13 版本。

Vulnerability Title
Apache CXF: Inoperative max_age authentication-freshness check in OidcClientCodeRequestFilter
Source: CVE Program / CVE List V5
Vulnerability 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.
