CVE-2026-85317

/// Technical description

Use of Cache Containing Sensitive Information 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.

The OAuth2 client token cache is global to the JVM, and its key omitted several of the fields that determine what a token actually authorises: the requested scope, the resource indicator, and the token endpoint the token was obtained from. Two endpoints differing only in those fields therefore shared a cache entry, and an endpoint could be served a token minted for a different scope, a different resource, or by a different authorization server. The consequence is a request carrying broader authority than the endpoint was configured for, or a token presented to a party it was not issued for. Reaching it requires a deployment that configures more than one OAuth2 endpoint differing in exactly those fields, which is why the severity is assessed low.

Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on
