title: "Apache Camel Security Advisory - CVE-2026-85316"
date: 2026-10-15T10:00:00+02:00
url: /security/CVE-2026-85316.html
draft: false
type: security-advisory
cve: CVE-2026-85316
severity: MEDIUM
summary: "Camel-Platform-HTTP: unintended proxy mode - proxy mode was selected by testing whether the configured path started with proxy, so any path beginning with those characters silently became a proxy endpoint"
description: "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."
mitigation: "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."

affected: "From 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1."
fixed: 4.18.5, 4.22.1 and 4.23.0

The JIRA ticket: https://issues.apache.org/jira/browse/CAMEL-24455 refers to the various commits that resolved the issue, and has more details.

The fix was merged on main in https://github.com/apache/camel/pull/25833 (commit 7abf13b2b314f40b8e76af3ba655266b57ff5e20), backported to camel-4.22.x in https://github.com/apache/camel/pull/25940 (commit 260989268cbc6d258b1fcba63770be8ebbec40cb) and to camel-4.18.x in https://github.com/apache/camel/pull/25942 (commit af1efbcccf5882b1ef0094db718972da3190e7e9).

The issue is classified as CWE-1220 Insufficient Granularity of Access Control. The camel-4.14.x line reached end of life before this fix and does not receive it; deployments on 4.14.x should move to 4.18.5 or later.
