Doc Text:
A flaw was found in the Apache Camel HTTP component. This flaw leads to information disclosure when the component is configured to automatically follow HTTP redirects. The client improperly forwards sensitive authentication credentials, such as OAuth bearer tokens and basic authentication credentials, to the redirected destination host. A malicious server or an attacker capable of modifying server responses can redirect requests to an attacker-controlled host to capture these credentials.

Description OSIDB Bzimport 2026-10-19 10:52:35 UTC 
Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Camel HTTP component.

This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1.

Two paths handed credentials to a redirect target, which is a host chosen by the remote server rather than by the route, once followRedirects=true. OAuth2ClientConfigurer registers its interceptor with addRequestInterceptorFirst, and HttpClient runs protocol-level request interceptors inside ProtocolExec, which sits below RedirectExec in the exec chain; the interceptor therefore ran again for every redirect hop and re-attached Authorization: Bearer  to whatever host the Location header named. Separately, credentials were registered against an AuthScope matching any host, so basic and digest credentials were presented to a redirect target as well. A remote endpoint - or anyone who can influence its responses - could therefore collect the bearer token or the configured credentials simply by answering with a redirect to a host it controls.

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. Credentials are now sent only to the authority the endpoint was configured with, and are not re-attached when a redirect crosses to another host. For deployments that cannot upgrade immediately, set followRedirects=false on endpoints that carry credentials, and handle any redirect explicitly in the route so that the destination is chosen by the route rather than by the remote server.
