Apache Camel Netty enables Java deserialization by default. Apache Camel 2.22.x, 2.23.x, 2.24.x, 2.25.0, 3.0.0 up to 3.1.0 are affected. 2.x users should upgrade to 2.25.1, 3.x users should upgrade to 3.2.0.
HtmlUnit prior to 2.37.0 contains code execution vulnerabilities. HtmlUnit initializes Rhino engine improperly, hence a malicious JavScript code can execute arbitrary Java code on the application. Moreover, when embedded in Android application, Android-specific initialization of Rhino engine is done in an improper way, hence a malicious JavaScript code can execute arbitrary Java code on the application.
Apache Camel prior to 2.24.0 contains an XML external entity injection (XXE) vulnerability (CWE-611) due to using an outdated vulnerable JSON-lib library. This affects only the camel-xmljson component, which was removed.
Apache Camel's File is vulnerable to directory traversal. Camel 2.21.0 to 2.21.3, 2.22.0 to 2.22.2, 2.23.0 and the unsupported Camel 2.x (2.19 and earlier) versions may be also affected.
The camel-hessian component in Apache Camel 2.x before 2.19.4 and 2.20.x before 2.20.1 is vulnerable to Java object de-serialisation vulnerability. De-serializing untrusted data can lead to security flaws.
The camel-castor component in Apache Camel 2.x before 2.19.4 and 2.20.x before 2.20.1 is vulnerable to Java object de-serialisation vulnerability. De-serializing untrusted data can lead to security flaws.
