CVE-2025-30177
Apache Camel Missing Header Out Filter Leads to Potential Bypass/Injection Vulnerability
Description
Bypass/Injection vulnerability in Apache Camel in Camel-Undertow component under particular conditions. This issue affects Apache Camel: from 4.10.0 before 4.10.3, from 4.8.0 before 4.8.6. Users are recommended to upgrade to version 4.10.3 for 4.10.x LTS and 4.8.6 for 4.8.x LTS.
