CVE-2026-80312— Apache Camel: Camel-OAuth Authentication Bypass via Fail-Open Processors

Quick assessment

Affected
Apache Software Foundation Apache Camel
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.

Apache Camel OAuth 组件存在身份验证不当的漏洞。 受影响版本： Apache Camel 4.11.0 至 4.18.5 之前（不含 4.18.5） Apache Camel 4.19.0 至 4.22.1 之前（不含 4.22.1） 问题描述： 用于保护路由的 处理器在无法完成身份验证时，未终止消息交换。本应在认证失败时终止路由并向调用方返回错误，但实际却继续将控制权交还给路由，导致请求如同认证成功一般继续流向受保护端点。这造成了一种“失败即开放”（fail-open）的身份验证防护机制：未经验

Vulnerability Title
Apache Camel: Camel-OAuth Authentication Bypass via Fail-Open Processors
Source: CVE Program / CVE List V5
Vulnerability Description
Improper Authentication vulnerability in Apache Camel OAuth component. This issue affects Apache Camel: from 4.11.0 before 4.18.5, from 4.19.0 before 4.22.1. The camel-oauth processors that guard a route did not stop the exchange when authentication could not be completed. Where a failure to establish an authenticated session should have terminated routing and returned an error to the caller, the processors fell through and returned control to the route, so the request continued to the protected endpoint as though authentication had succeeded. The effect is a fail-open authentication guard: an unauthenticated caller reached whatever the route did next. The condition is reached on the ordinary request path of a route configured to require OAuth, and needs no special configuration or prior access on the caller's part. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. The processors now stop the exchange and set the appropriate error status whenever an authenticated session cannot be established, so a failed authentication no longer reaches the protected part of the route. For deployments that cannot upgrade immediately, place an explicit authorization check after the OAuth processor rather than relying on it to halt the exchange, and verify that the route stops on failure.
