Medium [CVE-2026-85313] Permissive Cross-domain Policy with Untrusted Domains vulnerability in Apache Camel Jetty component
CVE-2026-85313Source published Source updated
Permissive Cross-domain Policy with Untrusted Domains vulnerability in Apache Camel Jetty component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. Setting enableCORS on a Jetty endpoint installed Jetty's CrossOriginFilter with its stock defaults, which accept every origin and allow credentials. An operator asking for CORS therefore obtained a policy that lets a page on any origin make credentialed cross-origin requests to the endpoint and read the responses, without any indication that turning the option on had chosen an allow-all policy rather than an empty one to be filled in. This is the same defect class as the platform-http-vertx advisory published alongside it, in a different component. Upgrade to Apache Camel 4.23.0, which fixes the issue.…

- Mitigation guidance
- 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. enableCORS no longer grants credentials to an origin the operator did not name.
- For deployments that cannot upgrade immediately, configure the CrossOriginFilter parameters explicitly rather than relying on what enableCORS installs, naming the allowed origins.
