What to do
Solution (from the CVE record)
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. Proxy mode is now selected by an exact path match rather than by prefix.
Workaround (from the CVE record)
For deployments that cannot upgrade immediately, rename any endpoint path that begins with proxy but is not intended to be a proxy.

Description
Apache Camel: Camel-Platform-HTTP Unintended Proxy Mode via Prefix Path Matching
Insufficient Granularity of Access Control vulnerability in Apache Camel Platform HTTP component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The component decided whether an endpoint ran in proxy mode by testing whether its configured path started with the string proxy, rather than by matching the path exactly. Any endpoint whose path merely begins with those characters - proxyStatus, proxy-config, proxying and so on - therefore became a proxy endpoint without the route author asking for it. A proxy endpoint forwards requests onward, so an endpoint that was intended to serve its own content instead relays traffic on behalf of whoever calls it, which is both a request forgery primitive and an exposure of whatever the forwarding path can reach. 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. Proxy mode is now selected by an exact path match rather than by prefix. For deployments that cannot upgrade immediately, rename any endpoint path that begins with proxy but is not intended to be a proxy.
