CVE-2025-30177: 
Java vulnerability analysis and mitigation

CVE-2025-30177 is a Bypass/Injection vulnerability discovered in Apache Camel's Camel-Undertow component. The vulnerability affects Apache Camel versions from 4.10.0 before 4.10.3 and from 4.8.0 before 4.8.6. The issue was identified on April 1, 2025, and received a CVSS v3.1 base score of 6.5 (Medium) (CISA-ADP).

The vulnerability exists in the custom header filter strategy used by the Camel-Undertow component, which only filters the 'out' direction while failing to filter the 'in' direction. This implementation flaw allows attackers to include Camel-specific headers that can alter the behavior of certain Camel components, such as the camel-bean component or the camel-exec component (CVE-MITRE).

When exploited, this vulnerability allows attackers to manipulate the behavior of Camel components through header injection. The impact primarily affects applications using the Camel-Undertow component, where attackers can potentially alter the execution flow by injecting malicious headers (NVD).

Users are recommended to upgrade to Apache Camel version 4.10.3 for 4.10.x LTS and 4.8.6 for 4.8.x LTS. These versions contain the necessary fixes to address the vulnerability (CVE-MITRE).
