What to know
- What it is
- 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…
- Affected
- Apache Camel before 4.18.5, 4.22.1
- Fix
- Upgrade Apache Camel to 4.18.5 or 4.22.1 (whichever matches your release line), or later.
- Exploitation
- Public proof of concept
Story map
At a glance
Apache Camel: Red, act today. Apache Camel has a 'Path Traversal' vulnerability in its Azure Files component, allowing an attacker to access files outside the intended directory. An attacker could read, write, or delete files on the remote server.

Original 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 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 cache key now includes every field that shapes the token, so entries are no longer shared between endpoints that differ in any of them. For deployments that cannot upgrade immediately, run endpoints that differ in scope, resource indicator or token endpoint in separate JVMs so that they do not share the cache.
